That may be true, but it is hard to tell from the available
documentation; gnus-list-identifiers isn't mentioned anywhere in the
Gnus manual and its docstring simply states:

     Regexp that matches list identifiers to be removed from subject.
     This can also be a list of regexps.

That is not my experience from my tinkering with it.  The variable
shows up in M-x customize RET gnus-summary-format RET as a setting
that modifies the subject in the summary listing.  Also, if you set
gnus-treat-strip-list-identifiers to 'head, article treatment will
remove the prefix from article subjects as they are displayed.

All this works just fine if I set gnus-list-identifiers globally (with
setq or set-variable).  What I would like is a way to set this on a
per-group basis so that I don't risk hiding parts of the subject in
other, unrelated, news group and mail folders.  What I was pointing
out in my original message was that this does not seem to work if you
just set it as a group-local variable (through the group properties).

If this is not currently possible, please regard this posting as a
feature request.

However, I would like for it to apply to only a select group of
folders.

This won't work for my setup, though, since I read all my mail from an 
Imap server and do my mail splitting with procmail at the server end.
