First, I must apologize for wrong advice (you should not answer such questions

No, wrong. _match has absolutely nothing to do with matcher-list style (that
was introduced only recently). _match was first "alternative" for
GLOB_COMPLETE option. It tries to match the list of possible completions
against pattern on command line. This works for _every_ completion (while
GLOB_COMPLETE worked only for files). But _match never tries to *expand* the
pattern - that is what _expand is for.
matcher-list is used to set global "matchers" - e.g. to do case-insensitive or
partial-word completion, like completing c-w to complete-word :-)) or g_c to
G_c to globcomplete.

Thinking about it, I believe, that _match would be the correct completer to do
it. There are many cases where we simply cannot do expansion at all - option
names, widget names etc etc etc. So, consider something like
WIth _match this enters menu completion - but _expand_word (I tried it) gives
you nothing. So, there seems to be no way to just insert all matching choices.
While _expand (and friends) may be useful at times, _match just seems to be
more powerful. (Of course, another general solution is to have widget that
would insert all listed choices at once. Was not it discussed once?)

Actually, no. It works in this case only because file completion itself is
using globbing - that is, the set of possible matches is determined by pattern
on command line. But the original wish was:
the * gets replaced with all the choices that the completion system
returns at that time (i.e., whatever glob pattern I've typed should be
applied to the completion choices rather than to files)?
It is exactly what _match does ... without giving you the way to insert all

No. See above the description of _match.
