it seems to *ME* like a simpler solution to the original problem would have been to simply STRIP any DKIM out of the original messages, and continue to munge headers and footers like mail list reflectors have been doing for decades.
That wouldn't help; DMARC policies are based on the From: header. If you want to munge messages from DMARC-reject senders you need to replace the From: header with your own.
Email doesn't work the same as it did decades ago. Senders need to keep up.
