[Mailman-Users] DMARC and From header munging

It occurred to me that one possible variation on From: header munging
which wouldn't break any applications depending on this being an actual,
working address for a post's author, while still passing DMARC
authentication, would be for Mailman to change the From: address to a
VERP-like address with the author's address encapsulated within an
address @ the list server.  Any mail received by the list server for
this address would have its address parsed by Mailman and be redirected
to the original author's real email address.  Would this pass RFC
