Isn't that exactly what p=reject implies? If so, the logical behaviour
for all list software would be to check the DMARC record for the
originating domain of each message, and bounce it if p=reject.
The question is which is more or less unfriendly?
1) Forbidding yahoo.com users from participating on mailing lists
2) Rewriting the from field of yahoo.com users.
I could easily see the mailing list software making this be
configurable, so it's up to each mailing list admin. :-)

P.S. #1 could also be combined with a nice message inviting the
yahoo.com user to find another e-mail provider.
