That was sort-of the idea, but it requires mail server admins to decide which ARC signers (i.e. mailing list servers) to trust. Recently gmail haven't even been trusting mailing list servers to send emails with the same message-id to multiple recipients... Don't use gmail unless you don't mind missing some mails. I've got to say, I find the From rewrites less annoying than not scrubbing MIME parts, though I'd prefer if Reply-To was set (to list+sender, leaving any Mail-Followup-To in place). Many lists have done this (often for all senders, not just those with published DMARC policy) and, after a period of adjustment to get used to it, it's not so bad.
