The motivation sounds good, but the minibuffer prompt always offers one
more choice, i.e. C-g. So accepting the only choice without prompting
might end up being a bit too eager in some cases.

I think so, yes. So I suggest you look for callers where that could be
used, and if they are common enough, we could consider adding a special
value of `require-match' which would allow such a short-circuiting.
