AFAICT the only other option is munging the From without enclosing the

it's still going to break things badly enough that I'm not sure it's a
worthwhile improvement.
The readymade mitigations for DMARC in mailman 3 are
"munge_from" and "wrap_message". The fact "wrap_message" messes
around with signatures in mutt is definitely not a good sign,
and "munge_from" will change the author's email and name from
the perspective of git-am.
The middle way could be to patch mailman 3 to "munge_from" while adding
the correct "From:" as the first thing in the body of the message if it
doesn't contain one already. This will make git-am pickup the correct
author's details and it should be some simple logic.
Unfortunately, changing the message body will break the DKIM message integrity
(body hash)...
