It does not matter, you can adopt it right away to minimize some
problems with the hand editing. What I wish to say, we do not need a
"standard" to make it little easier for others. The Mail-Followup-To
is just making it little easier to avoid Cc-ing people who need not be
Cc-ed or to find out the mailing list address.

Person could as well do it by hand.

I see my habbit was bad to use group reply, from now on I will use
list reply, and honor other people's Mail-Followup-To header. It is
kind to do so.

Sure, good thing to switch conversation from one email address to
other, but correspondent may not honor it, so I do it for as long as
necessary or even tell to person to answer me on different email address.

That is what I was using, but that is not quite correct in mailing
lists. From now on I will use list reply that recognizes the mailing
list as I configured it, and I reply to the list, not to sender.

Those options are settable by every email user if they want it. People
do not know how maybe, but email has headers, and back in time headers
were edited by users. Today they can still be edited.

We are hacker community here.

Please see settings for Thunderbird for Mail-Followup-To:
https://wiki.mozilla.org/Thunderbird:Help_Documentation:Mail-Followup-To_and_Mail-Reply-To

In message mode, there is also Follow-up header:
https://www.gnu.org/software/emacs/manual/html_node/emacs/Header-Editing.html

so it means it can be also customized and provided.

Also search here for "followup":
https://www.gnu.org/software/emacs/manual/html_mono/message.html

Quote:

The message-use-followup-to variable says what to do about Followup-To
headers. If it is use, always use the value. If it is ask (which is
the default), ask whether to use the value. If it is t, use the value
unless it is ‘poster’. If it is nil, don’t use the value.
