It has just caught my eye that both [5] and [6] are marked as conjunctions, have similar glosses, and both link back to て. It seems there was both a cross-reference from で to て and one from て to で, and that the previous [4] snatched the one coming て when I raised it to [5].
I shifted them around to circumvent this and have also removed the cross-reference leading from here as it was seemed redundant to have them go both ways.

I agree with Marcus that にて should be split out. We've moved away from these sorts of merges in recent years.

daijs, daijr
https://kobun.weblio.jp/

で Is itself a contraction of にて, hence the meanings are identical*. I think keeping it in one entry reinforces the notion that they are related and used as alternates of one another - plus it saves the need for an additional entry that would be essentially copy-and-pasted from this one.

*I cannot recall ever seeing にて used for the sense I have just added and indeed upon searching for an example I could not find many. 
Further, that sense is not even listed under the にて entry for the daij's, which at the very least implicates にて is not commonly used for it.

I also went over to the classical Japanese dictionary of the link above, and it seems にて did not originally hold that meaning.
Still, I do not think much would be gained from a split. Worst case scenario, someone will start using にて left right and centre, but even then, they would at most sound odd while still being understood by any native speaker*. 

*Dialectal variation sold separately.

Separate issue but I think we should undo the にて merge. Even if the meaning is identical (I'm not sure whether that's the case or not), it's a different register.

daijr, particularly on（イ）: 〚（２）動作・作用が行われる時を表す。（ア）動作が行われる時期を表す。「では」「でも」の形をとることが多い。「現在―は，簡単に解決する問題だ」（イ）動作・作用の期限・限度を表す。「新幹線は一時間―二百キロも走る」「一〇分間―答えてください」〛

Added a new sense, made it [4] and moved the previous 4th-6th senses up a number. I acknowledge the note is rather long but "quantifies limits of action" by itself seemed too abstract to be informative and I could not devise anything better. Also made minor alterations to 6 as it was misleading: "indicates continuing action" implicates a progressive action, which is not the case here. I still would like to move [6] over to the て entry as another reading.

Anyhow, as justification for the new sense a few sentence fragments:
”あと十人で終わる” = "Will end/(after)  in ten (more) people"
"五分ですべてを話す" = "Speak everything in/within 5 minutes"
"一回で済む" = "Settle/end in one instance" 
”五人で行く”　= "Go in five (people)"
The existing senses cannot properly account for these uses in the manner they are currently distributed and explained, they could be overhauled but I think this use is sufficiently distinct to warrant another sense.

I agree. That sort of thing is more relevant to a dictionary of grammar and usage.

I don't think　で itself in that sentence has any meaning 
beyond "is". You could say "Carl being Carl" in English 
for example. 

That said, I think "is" could be more explicitly define. 
I mean just like with the -て form there's a suggestion 
of causality/time but basically, doesn't it mean "is x, 
and..." rather than just "and then"?

Well, my approach to dealing with the additive versus sequential distinction was to add that other sense. Personally, I feel that if distinguishing those two is too much, then we cannot really justify all the other senses, which arguably bear a less important contrast. And if that is so... we might as well just reduce them all to a single sense.
As to the terminology, I am not sure if "additive relation" is immediately intuitive, but probably should be fine given that it is accompanied by a translation.
In any case, my input on how to word this can be found under my older proposal - just scroll down a bit and you will find an obscenely large change log under an edit by Mr. Breen, which was that proposal being reverted. Sadness, sadness.

Now; the reason why I made で a reading and the others not, is because it makes the entry and its notes shorter. 
て and で are the endings of all て forms; so - in theory - one should be able to identify all instances by those endings. Thence my note says "becomes で after 五段 verbs ending in ぐ, む, ぶ or ぬ" instead of "becomes いで after 五段 verbs ending in ぐ; becomes んで after 五段 verbs ending in ぬ、ぶ or む". 
Consider also that adding って means that we are missing んで, いで and いて in the readings and notes. Needless to say, the readings might be fine but such notes would end up covering a metric mile - which I am not necessarily against, but I am not the one you will need to convince anyway so...

Regarding your first point, I had that in mind, but I hadn't yet thought of a way to deal with that. I feel like having two senses may be a bit much. 
Perhaps having "indicates sequential or additive relation" works? That should be somewhat clear then with the glosses.
Or maybe "indicates simple conjunction or sequential relation"?

Regarding the attachment note, I agree it's probably better to leave it out here. It'd be more of a matter of formality rather than practicability.

Since we are at 音便 already, this entry also needs to mention って, as in 知りて ＞ 知って, 立ちて ＞ 立って and 買ゐて＞買って.
I propose just adding that to the note.

Regarding [1]: The conjunction is not necessarily always sequential, it often its, and て has a tendency to chosen over the 連用形 if the relation between the conjuncts is sequential, but it is not restricted to those uses.
The most obvious case is with adjectives: 「黒くて高い」can be freely rephrased as 「高くて黒い」since no sequence is implied. This is why my older proposal had 7 senses as opposed to the current 6 - it had an extra one for the bare, non-sequential conjunction, which was [1].


Regarding compound verbs： I am referring to cases wherein verb + て + verb is analysed as just one verb. This use, like pretty much all others, is rooted in sense 1. Albeit rarer than the 連用形 compounds, it works under the same principles.
For example, 遣って来る, despite clearly being made from やる＋て＋くる、is given its own entry in Daijirin, Daijisen, Shinmeikai and Koujien. In all of these cases, it is listed as a カ変, rather than the expected 連語. There are more entries like this such as 取って代わる.
Perhaps an even better example is 打って変る, whose meaning is not really the sum of its parts.

Regarding the [conj] particle: As briefly mentioned above, pretty much all senses of て are rooted in its role as a conjunctive (which itself is rooted in its origin as the 連用形 of the ancient perfective auxiliary つ), with the exception being senses [5] and [6] of the current proposal wherein it cannot really be analysed as a conjunction - which is why I did not put in the tag and am thus removing it from [5]. 
I also have reverted the term 'subsidiary' to 'auxiliary' as I think the latter is more common and more likely to be immediately understood (plus, it is 1 letter shorter, which will surely make all the difference).

And lastly, stem connection: While the stem for the て form is regarded as being the 連用形 due to the etymological origins of the 音便形 as a sound change of the 連用形 + て, in practice the 音便形 is its own inflection.
As such, writing either 連用形, continuative form, or -masu stem, will not allow a reader to correctly deduce the inflection - instead they would end up producing an inflection right out of Old Japanese, such as 書きて instead of 書いて, etc. - this is why both foreign Japanese textbooks and native Japanese textbooks aimed at foreigners almost unanimously teach it as "て-form" or て形、 as an inflection itself.
I am not sure if there is a good way to convey that in this dictionary (maybe do something on the 音便形 page and cross reference it here?) as this is complicated by the fact that the "音便 stem" involves alteration of the verbal root.
I.e. Kak-, the root 書く, must lose the final k, receive the left-over -i from the 連用形, turn into Ka-i- and only then connect to て - which is unlike the other stems that are all simply concatenated onto the root: Kak-a/i/e/o/u.
Either way, I would drop that part of the note.

Firstly, I intended to submit my draft for this entry in this comment box at the bottom instead of outright changing all you have proposed (which I do agree with). 
However, when then attempting to submit that I get the error "The requested URL's length exceeds the capacity limit for this server.", which I haven't encountered so far.

ーーーーーーーーーーーーーーーーーーーー
＞ As I am editing this, [3] Is being shown as "[prt][col]" in the preview instead of "[prt,col]" despite having been formatted like the latter [...]
I reckon that is because they belong to different tag classes. [prt] belongs to the POS tags, while [col] is a misc tag.

＞ I fear that might lead a reader to believe that said note applies only to [1], which would be misleading.
I fear so too
ーーーーーーーーーーーーーーーーーーーー
Being a (relatively) new contributor to JMdict, I've never really looked at this entry, but I absolutely agree that the former version is very much insufficient. 
ーーーーーーーーーーーーーーーーーーーー
Also, I see that you've brought up the point about 接続助詞 below. The good news is that a [conj-prt] tag will most likely arrive in the near future, as I've raised that topic in the github issues.

Could you elaborate on sense 2 "particle used to form compound verbs"? I don't quite see that in references, since it's usually the bare 連用形 used for this purpose.

Stem attachment information tends to be included. However, adding the typical "after the -masu stem of a verb" doesn't suffice here. Perhaps "After the continuative form" is appropriate.
   連用形 and the likes are typically not used in sense notes in JMdict. Note that "continuative form" is searchable in JMdict and leads directly to the entry for 連用形.

The references I consulted (Shinsen, Sankoku, Daijirin) class the current sense 2 as "接続助詞" as well, so I added [conj] for now.

I see that the support has previously been lacking, but I believe that having separate senses for the different uses of the conjunctive aspect is necessary. 
   Compare shinsen above, which is quite neat, but not achievable in JMdict in that fashion.  
   I would argue that the entries for the most used "words" (items would be better), deserve the most care, i.e. specificity. And that does take time in some cases
ーーーーーーーーーーーーーーーーーーーー
Thus I propose something along the lines of this (subject to refinement)

Well, I did say that they were there to be picked out, and that only [1], [6] and [7] were strictly necessary. I still stand by what I said that this entry cannot stay like this, so, let us try that.
Repeating the note on で in every sense might be unneeded, maybe remove it from [2] and [3], leaving it only on [1]. However, I fear that might lead a reader to believe that said note applies only to [1], which would be misleading. Really wish we had notes that went over the entire glossary...

Changed [aux] to [prt] as it is classed as a 接続助詞. Completely changing glossary as "Indicates continuing action" will likely lead anyone learning of this word through this entry to think of a continuous verb rather than a conjunction.
Senses are based on the references listed, mainly daijr, they are not absolutely exhaustive but these should be the main ones. I opted to make [1] what it is as most other senses can be imposed upon it by context.

If accepted, I would like to suggest deleting the 5th sense of the entry on ～で that leads here: it is same word and the changes to notes in this entry should make it unnecessary.

actually, come to think of it, れる and られる could be merged with a note.  they're already sufficiently well-documented.

they have to be merged because one is merely an alternate pronunciation of the other that occurs with certain verb forms. れる and られる are clearly more divergent than て and で.

in addition, there is already an existing entry for で, and we try to avoid having entries with identical headword/reading combos.

The notes only do two things: tell you what it is and tell you what it does. Do you presuppose that a reader does not wish to know either or neither of these things?
Of course shoving 連用形 or "conjunction" in there will not automatically allow them to directly download information concerning those concepts unto their brain, I truly hope you did not think this to have been my intent. 
The terms are put there so that the reader may research them on their own, they can even be researched back with this dictionary if someone wishes to research through translation. Could you construct an argument against these points, so that we can have a productive discussion and make a better entry?
The information is not there to "cater to grammar nerds" as you so creatively put, it is there to teach the language: grammar plays an important part of second-language acquisition for many, especially adults, even more so when there is such a disparity between the structures of Japanese and several Indo-European languages. Did you learn Japanese without studying any form of grammar? I would doubt that unless you grew up using Japanese.

"連用形" etc. isn't helpful. 99% of users won't know what it's a reference to. If you really were as smart as you seem to think, you'd realize the goal here isn't to cater to the 1% elite grammer nerds

Entry was missing the information that ず can form a conjunction.
Added second sense as terminal ず can still be found in set phrases as well as certain media.
Opted for 連用形 and 終止形 over translations as the original Japanese can likely be researched with less potential of wrong results than something such as connective form or terminal form, they can also be looked up within the dictionary whereas translations cannot.

i agree.  if it's not in a dictionary, the right place for it is probably the example sentences.

I'm just generally opposed to adding long, non-idiomatic expressions that aren't in the refs, regardless of how common they are.

rolls (or doesn't roll) off the tongue is 
very relevant either, nor how recent it

I'm not sure this is worth including. It's a full, modern sentence, and not found in any refs. There are a lot of variants with やらないで、やらぬ、よりも, etc.

I don't have much to add to this discussion. I think it might be worth more than the average -がる form of some adjective for precisely the reasons already given in your discussion. As for mentioning the usage restriction, that's my fault for forgetting that, thank you for pointing it out.

GG5, ルミナス and プログレッシブ all have it as entries; not subentries/examples. I'd keep it.
I don't think the "appear to/seemingly" works - it gives the impression of insincerity, which is not the case.
I'll approve and reopen.

What I'm getting at is that there's likely hundred of adjectives marked 派生:がる in daijisen (even 甘い has it). How many of those do we need as entries? Not that many, I tend to think, just like we don't need all that many -さ entries.

Is it an entry or does it just appear in example sentences?

We have a lot of 〜がる entries;  I wouldn't knock this one back on those grounds. The fact that several JEs include it indicates a level of importance/relevance. I think a note could address the focus.
I'll reindex that sentence.

Standard use of -がる and the entry fails to mention this form can't be used to talk about your own feelings. I don't think this is helpful.

Literally every ref that has an example, except gendai (「寝しなの電話」), uses a ━に example. 
But the kokugos still have 寝しな as the entry.

I found it hard to formulate a distinct noun gloss here, but I think this is still better than having two seperate entries, or just the adverbial one. 

Encountered it as ～に here: https://www.ctk.ne.jp/~yamamoto/hida_dialect/grm_setsubigo/garu2.html

Kokugos and JEs only have the first two senses, and pretty unanimously tagged as 《俗語》.

About the sweet meaning: https://ja.wikipedia.org/wiki/チンコロ

俗語辞典 has the "snitch" meaning. There is also a meaning "low life" or "inferior person"
About that: 
 《2》 《1》の子犬という意味から、ちんころは地位も力もない、取るに足らない者＝小者という意味で使われる。

jawiki has チンコロ for the gambling game: https://ja.wikipedia.org/wiki/チンチロリン

About the hair style: https://www.happilyphoto.jp/column/604703/#:~:text=●ちんころ・かのこ「ちんころ」,ていた髪飾りです。

Explained as a kind of hair accessoire here, not a hairstyle.

The snitching sense could have both transitivity tags, right? Many senses, I added all I could find. Definitely needs a thorough check, this was a lot of information.

https://www.tutitatu.com/「チンコロ」の使い方や意味、例文や類義語を徹/

in the ref. link above this term is written in katakana and it has as much as 5 meanings, for example it is used also to refer to "cee-lo (dice gambling game)" (チンチロリン), but I've only added the one I've encountered in game and the one recorded on GG5.

Also the second meaning used in Final Fantasy 14 was in fact in katakana, should that be a separate entry then?

I've encountered the 2° meaning on FF14, and I wouldn't be surprised if the Yakuza game series would use it as well. Is it a "vs"? Moreover should it be marked as slang?
