fido-mode doesn't change icomplete-mode. It shouldn't, at least.
It just uses it as a library.  And surely if it's a bug in fido-mode,
surely it needs fixing _there_  and not elsewhere.  But it seems
not be the case (at least with your latest proposal), so you have
me confused.

So much time has passed that I don't remember what the fix was anymore.
Have you pushed it?  I don't see it in emacs-27
