It appears that MFT proponents cannot agree what it is supposed to do

In fact, all of us are in perfect agreement as to what Mail-Followup-To
does: it replaces To etc. as the default followup target, in exactly the
same way that Reply-To replaces From as the default reply target.

Comments such as ``In this case, Mail-Followup-To includes both of the
crossposted lists'' are simply _examples_ of how senders commonly use
and benefit from Mail-Followup-To. They don't change the _meaning_ of
the field. The Mail-Followup-To field always means the same thing: it
replaces To etc. as the default followup target. Nothing more, nothing
less.`

Yes, but Mail-Followup-To is no use unless it is clear which of the "reply
buttons" causes it to be invoked in preference to From/Reply-To. Jacob
Palme's original draft proposal always presumed that it would somehow be
apparent when a "group reply" was wanted, but the only really satisfactory
way to ensure that is a separate "Reply-to-List" button.  Without that,
the MUA is going to have to resort to some rather messy heuristics.
