That approach would also have the effect of adding back in to $PREFIX
characters that were shifted off to $IPREFIX.

Another option might be to filter out just quoted aliases and complete
only them:

  aq=( "${(@Qk)aliases}" )
  print -lr --  "${(@k)aliases:|aq}"

Intuitively I would think this should be an additional effect of the
existing -Q option.

The trouble is that completion fully strips quotes and parses the
command-line into words very early on. There's no getting the original
form back, at least not in a way where you know which character
corresponds to which. It would needed a layer of abstraction such as a
rope data structure when unquoting.
