Mediators, like mailing lists, take final delivery and post a new

It's legitimate for a mailing list to rewrite the author, but it would
be wrong. :-)
More seriously: If the mailing list wishes to express that I am the
author of *this message*, then I belong in the "From:" field. That
differs semantically from forwarding a message authored by me; then the
list is saying that the list is the author, and it is simply quoting me,
but that the list is the entity that should be considered to have
written the message. For most mailing lists, that seems like the wrong
semantics to try to convey.
There should be a mechanism for an author to send a message to a mailing
list, granting the mailing list permission to redistribute that message,
and have that permission conveyed to the mailing list recipient such
that when the mailing list recipient receives the message, they can
assure themselves that the originating domain is OK with that
redistribution. Sounds like some protocol which could be written.
(If the originating domain is expressly *not* OK with the
redistribution, the mailing list should bounce the message back to the
author saying as much.)
