Well, you can argue this on a philosophical basis, or on an enginerring "best
practice" basis, but in the real world you only have so many things that a user
can filter on. Netscape Mesenger only allows specific pre-configured headers to
be used, and List-ID isn't one of them. To, CC, subject, sender, date, status,
priority, and body. Body, of course, is incredibly slow, so I never use that one.
Eudora adds "Any Header" which would at least allow List-ID to be noticed, but
only in a context in which some string (like "mailman-users") will appear
multiple times.

Maybe I should look again at moving my Messenger Mail to Mozilla, but previous
tests show it is only capable of importing about half of my In box, so I don't
exactly consider that appealing.

In other words, the filtering is going to be done based on the capabilities of
the client. Something that is theoretically better may not be terrible useful.
