The alternative I suggested is 100% compatible with the installed base.  If a 
domain has published DMARC policy per RFC 7489, the proposed new approach will 
still find it.  I agree that something which would require existing DMARC 
records to be changed would be a non-starter.

I'm not sure how much more respectful we can manage to be.
