As I pointed out elsewhere (on the mailman-developers list) this is
just reinventing Usenet as a push medium.  Barry has already asked
that this conversion go there; Reply-To set.

However, it is often the case that even when themes apparently nest
(as "guitarist" nests into "musicians"), some people are interested in
a collection of "broad" threads from "musicians", some people want a
collection of "narrow" threads from "guitarists", and there is often
an overlap where it's not obvious whether it is of narrow interest or
broad interest, eg a new technique for guitarists that might have been
known by cellists, or maybe trombonists -- you don't know -- since
antiquity.  Cross-posting can't be eliminated; you can only help users
to recognize and organize the duplication.
