Just a short pre-answer to that point, because you got it wrong:

Of course it's wrong. I don't propose that. Sorry, my quoted sentence
above was not clear enough, please stick to the proposal I made.

Assuming you chose the option "reply to list" (option 2) according to my
proposal, the headers would look like:

From: stephen at xemacs.org
Sender: steve at uwakimon.sk.tsukuba.ac.jp
Reply-To: mailman-users at python.org
Cc: careof at somewhere.net (added to existing Cc:, but only if
careof at somewhere.net is not a member of mailman-users at python.org)

I don't see how this additional Cc: can be more dangerous, than what
Mailman is doing right now. The opposite is true, it fixes the
reply-to-all function, because the answer would also go to
careof at somewhere.net, what you explicitly requested by your Reply-To.

All my proposal is about, is bringing the reply-to-munging closer to the
RFC _and_ usability than it is now.

Reply-to-munging _is_ heavily used in existing Mailman installations. Why
not fix it then?
