It's not that I rather we didn't add [rK] to the 御犬舎 in "ご犬舎;御犬舎"; it's more that it should be rather obvious that the ご form is the common one, and hence the signal in the [rK] is a bit wasted.

There are some entries in which 御 doesn't make the form [rK]
(ご飯:御飯 seems to be 90%:10%). It's a bit of a stretch, but I don't
think having this metadata is completely without value. If nothing
else, I think it's good (for the sake of our mental overhead) to keep
rules and categories consistent with as few exceptions as possible.

I wasn't planning on hunting down all of the [rK] 御 forms; I usually
just submit edits for terms as I come across them in real usage. It
only takes me a few seconds to grab the n-gram counts and paste them
here, so it's no burden on my part. But if the editors would rather
that I not submit edits which only contain this information, then I
will respect that. Please let me know.

I agree. No harm tagging them, but probably not worth the effort.

There's nothing inherently wrong with marking 御- and -無い forms as rK, but I feel it's a little pointless. The original idea I had when I suggested it was mostly for it to be a study aid, to inform users they don't really need to bother remembering these kanji to feel they've "mastered" the word. When it comes to 御- and -無い, the kanji are common enough that everyone but the earliest beginners should be aware of them, and the usage of them is completely standard.
