Verifiable authenticity of email greatly depends on DMARC's success. Because without DMARC's success the authenticity of email can only be verified heuristically and not systematically. If mailing-lists configured old-style hinder the adoption and ultimate success of DMARC, then received email will not be able to be verified as authentic in any systematic way, but only heuristically. That greatly lessens the value of email as a viable medium for important[*] communications that users want to receive. [*] I define here "important" as: "potentially expensive for the user if missed and/or potentially expensive for the user if successfully spoofed". Therefore, as per the above reasoning, given that the "traditional practice of mailing lists adding tags to Subject and footers to the message body" breaks DMARC, it is also breaking the mechanism (DMARC) which could take email to the next level as a viable medium for important communications. I vote for steam-rolling mailing lists configured old-style to the history books. Mailing list operators just need to take ownership in the Header-From for the messages whose DKIM signature they break, and all is back to working great again! > > You say that as if a solution that works but you don't like is not > > a solution but a kludge. > > It is.

Well, I posit the user requirement is, at large, to take email to the next level a viable medium for important communications.
