I disagree, the same problem exists for prefix completion. Maybe it's
less frequent, but it exists nevertheless. Which brings us to the
reason why we don't currently ask: choosing the wrong name is harmless
because C-h f does not perform any dangerous operation that might lose
you some work.

Reread what I wrote: I said "indirectly".
It's related not for its functionality but because if we want to be able
to accept non-existing functions, then RET can't perform completion
any more.

That's almost already the case: it's fairly rare for Emacs completion to
use this kind of strong `require-match'.
