Eh?  It puts all matches into the command line without re-displaying
it after every match -- only redisplaying it at the end.

Yes, but that's not the real problem.  There are many different styles 
of how suffixes and all-matches should be handled (and that also
affects how prefixes are to be handled, as in your conv=value example).
I don't want to have yet another case of adding a bit and then some
more and some more and...

What I really want is to move more of the completion setup and
finalisation code into shell code, to make it more flexible and to
allow more people to play with it.  Then I'd even like to remove some
of the options to compadd (-q, -r, -R -- especially -R).  That means
identifying stuff for which we need C-code support and adding builtins 
and/or special parameters for that.  Then we can hopefully remove the
suffix handling from the zle module, and probably even get rid of the
difference between normal and completion widgets.  For things like
auto-removable suffixes zle would offer a hook or something equally
generic (some kind of {pre,post}-command-hook).  The rest would be in
shell code with a function to register prefixes and suffixes and to
say how they should be handled in different situations.

Or something like that.  I haven't thought that much about all this
yet, because I don't have much time now.  We had some discussion about 
suffix handling some time ago (last year, I think), but I'd have to
search for it in the archive, too, because somehow it fell from my
todo list.  Ahem.
