Actually, mailing lists *can* implement DMARC, just not that way: Do a DMARC

the list's policies to conform to that message or reject it outright,
preferably with a nasty "find another a better mail provider" sort of message.
If the IETF wants to take a leadership position in regards to this issue,
perhaps someone could set this up.
The DKIM WG discussed this idea in RFC 6377.
