jitsuyo (どう仕様もない):「どうしようもない」の不適切な表記。漢字を用いる場合には普通「如何しようもない」などと書く。

仕様 is irregular here. The しよう in どうしようもない is the volitional form of する, not a noun. Note that daijs has 仕様もない for しょうもない but only 如何しようも無い for どうしようもない.

One more counterpoint to myself you might also consider:
どう仕様も無い[rK]
all else [sK].

This provides all of the "reasonable" kanji for the entry (如何 excluded).  I find that it can be easier to understand a long string of kana when you unambiguously understand the associated kanji form, even if the kanji are not ordinarily used.

While it's in my previous treatise somewhere, I'll just add succinctly "I agree".  Will try for some more condensed edits going forward.

I think all the kanji forms can be sK.

Most of the kokugo definitions for -好き terms include "また、その人". The original glosses were probably OK.
As for part of speech, some are nouns only, others are 名・形動. Meikyo has 「━の／な 連中」as an example for 酒好き, so adj-no is at least sometimes valid. Needs to be handled case by case.

I still haven't wrapped my head around what exactly happens when you drop が and change すき　to ずき.  I know in principal that you generally gain the ability to use の as a connecting form(where 好き is usually な), but that な also remains common.  This could be because the ずき form is now a noun, and の is how you connect nouns together. (I would think this would support almost all of these entries being [adj-na,adj-no,n]).

It certainly seems like most of these remain [adj-na] whatever the dictionary might otherwise suggest...  We aren't handling these consistently. Here's the first 1/3rd of our entries from an advanced search "ends-with-好き", "ends-with-ずき":
[n] 下手の横好き, 人好き, 子供好き, 客好き
[n,adj-na] 世話好き, 出好き
[n,adj-no] 女好き
[adj-na] 争い好き, お客好き, 交際好き
[adj-na,adj-no] いたずら好き
[n,adj-na,adj-no] きれい好き

These distinctions don't generally seem to be supported by the ngrams.  To take one example of an entry listed currently as [n]:
人好き	61235	  
人好きな	22042	 <- な is 1/3rd of all occurrences
人好きの	5929	  

One more (currently [n,adj-no])
女好き	85862	  
女好きの	14583	  
女好きな	10827	  <- な only marginally less common than の

I'm afraid I don't understand the grammatical nuances well enough to say what *should* be the case, but it is my impression that (at least grammatically speaking) most of the 好き/ずき-suffixed forms should behave the same in most cases.  But our entries are all over the map.

Does anyone have a better understanding here than I do?

We only have about 30 entries of this kind.  I'm willing to print all 30 on a sheet of paper and start surveying Japanese people ;).

Not rare, but the xref should probably be used in most everyday cases.

I get the feeling this is used especially in special explicitly-inclusive contexts.  This appears in some policy/legislative directives ("sibling abuse").  I saw as a translation for "all of my brothers and sisters who suffered under ..." in a dramatic speech(semi-figurative, members of the same race oppressed by another race. but it's sci fi, and it was a "collective" society, so who knows...).  daijs explicitly says same as senses [2] and [3].

「詮方ない」は、古めかしくて固い印象です。若い人が言ったりすると、とても違和感があります。よく使うのは、ドラマや小説で、偉くてある程度歳をとった人が言うセリフです。

そのようなことを議論しても詮方ないであろう。粛々と次の襲撃に備えよ。

1. add surface form
2. mark some [rK] and [sk].
3. mark [rare].  The hinative comment (last reference) is particularly detailed, not sure if that's enough for [form] or anything else though. (dictionary does not mark as such).

Reasonable number of book results.

Was going to change xref as [see=仕方がない[1,2]] because I'm not sure this carries any of the special nuances we've attached specifically to the どうしようもない entry. But I'm not confident, so I'm leaving it and just changing the simple things.

sankoku defn. in its entirety is "仕方がない".  
daijs. mentions どうしようもない.

為ん方無い is the daijs form. Of ~30 google book references, ~25 are dictionaries.  Leaving as [rK] because of daijs.

Actually have several reverso instances of this one.  This seems to be the correct term for the battleship usage.

Here is a completely modern manga reference. If the subject is historic naval warfare, this seems to be a relevant term.

Not trying to remove entries just for the sake of it.  

片舷斉射 entry was the most common form I found on the now-deleted 半舷砲 entry. 

reverso translates this as "broadside", and also doesn't seem to have any better Japanese translations for broadside in reference to firing guns from a battleship.

if you search google for "片舷斉射" and "broadside" (or "fire a broadside") together,  you'll see this noted in various references.

dictionary references report this as をする, and examples also use を行う, neither of which we have notes for. (ngrams agree)

deleted reference was "broadside fire", but it appears that the english gloss should just be "broadside", with 片舷斉射をする becoming "fire a broadside". The simple gloss would then need some clarification in an [expl] or parens. The [expl] feels like the most readily comprehensible approach, but maybe is more verbose than we'd like.

More general and figurative uses of "broadside" appears to be handled by 一斉攻撃. ("b(悪口の)一斉攻撃.").  

I initially simplified "a firing of all guns" to "firing all guns".... but I guess a "broadside" is in fact a single volley.
