OK. And I removed the こしゅう reading from the body odour entry.

Given that nikkoku is the only ref that has こしゅう as a reading for the body odour meaning, I think we can assume that it's rare (or archaic), and therefore it's probably not necessary to include a "body odour" sense on this entry.

Maybe this can be partly solved by adding a frequency tag to the other entry?

It's a complex issue that goes to the heart of our merging policy & style. 狐臭/こしゅう is in the main body odour entry (1570890). (I wish it wasn't but Nikkoku has it.) Also, the main use of 狐臭 is to refer to body odour, although I'm sure Japanese people would usually read it わきが in that context. As you have shown, 狐臭/こしゅう also means a wine smell. That's fine and it warrants an entry, but I don't think it appropriate that someone who looks up 狐臭/こしゅう gets an entry *only* about the wine smell (yes, most apps/sites would serve up 1570890 as well, but 狐臭 and こしゅう are a bit buried there, as that entry is mainly about 腋臭/わきが.)
I wouldn't really object to the body odour sense being dropped here, but I think there'd need to be at least a comment and perhaps an xref about it. Any thoughts from others?

But we already have an entry for the armpit smell sense. I don't think this is necessary.
