Big problem!

Let's say we get this mail

From: Robert Pluim <rpluim <at> gmail.com>
To: 積丹尼 Dan Jacobson <jidanni <at> jidanni.org>
Cc: Lars Ingebrigtsen <larsi <at> gnus.org>,  6615 <at> debbugs.gnu.org,  34130 <at> debbugs.gnu.org
Mail-Copies-To: never

Well, causally hitting S W to reply to all gives us a buffer with:

To: Lars Ingebrigtsen <larsi <at> gnus.org>
Cc: 6615 <at> debbugs.gnu.org,  34130 <at> debbugs.gnu.org
From: 積丹尼 Dan Jacobson <jidanni <at> jidanni.org>

Do you see the problem?

Gnus has blindly picked the **first** person from the CC list to become
the single To: person.

Yes, a proper mail needs a To: person. But it is a massive mistake to
pick one of the equal Cc: people to be the new To: person.

It was just like we were set up to redirect our anger at somebody else
via the silent booby trap Mail-Copies-To: never !

Solution: make all the people of the former Cc: and To: list now all equally
represented in a new single To:
To: Lars Ingebrigtsen <larsi <at> gnus.org>,  6615 <at> debbugs.gnu.org,  34130 <at> debbugs.gnu.org

Simple!

Furthermore, definitely give a warning:
'"Mail-Copies-To: never" header detected. Honor? [Y,n,?]'

And what if there were no Cc's or other To's ....

Anyway, the idea is to warn the user that he in now replying to someone else.
Also to eliminate making it look like we have chosen a special bystander
to now direct our wrath at instead of equally distributing it.

Yeah, that's perhaps not optimal, and since it's valid to put several
addresses in the To header, perhaps the best solution is (as you
suggest) just to put all of them in the To header.

Does anybody have an opinion here?

I don't think that's an issue -- it'll just use it in that case, if I
remember correctly.

Nobody had, so I've now done this change in Emacs 28.

I used to have one, but Iʼve given up on Mail-Copies-To: never, since
there are too many broken mua's out there (which combined with people
who do 'reply all' when they should 'reply to sender' and 'reply to
sender' when they should 'reply all' just makes me despair for the
human race).

OK.
