I'm all for doing this in shell functions, but zsh isn't strong enough
for that (yet). The problem is that things like multicomp only work
with menu-completion.

Question is, what excatly do we need to allow building arbitrary
completion lists in shell functions and have the code make them
conveniently accessible with normal completion. Maybe something like
`replace the current word with the prefix <a> and the suffix <b>,
placing the cursor between them'. But we would also need to be able to
return the whole completion list for automenu. Taking multicomp
(i.e. path) completion as an example that would mean to present either
the list of full paths or only the list of ambiguous path name
Thinking about the latter leads to the suggestion that such functions
may return: `we split the current word into <prefix><ambig><suffix>
at positions <p0> and <p1> and want <prefix> be replaced by <a>,
suffix by <b>, and for <ambig> we offer the list of possible
completions in $reply, now present that to the user'. But that sounds
pretty complex (in fact this is near to what the compctl code does
internally), so does anyone see a simpler solution?
