I t think your comments are compatible with DMARC being the
"interloper", as Stephen put it. DMARC (whether in general or in terms
of Yahoo's and AOL's use/misuse/abuse of it) is the interloper (i.e.
newcomer) that is in practice impacting pre-existing and legitimate
usage patterns.

I agree that the idea behind DMARC is a good one the reality is less good.

Whilst Yahoo and AOL are the ones who have chosen to use/misuse/abuse
DMARC in this way, it could also be said that DMARC (and all its backers
on its current form) are to blame precisely because DMARC *allows*
Yahoo's/AOL's behaviour. If the standard has been properly finished and
properly thought through from all angles then ways could surely have
been found to allow it to be used without harming existing,
standards-compliant behaviour. The consortium behind DMARC simply
weren't willing to wait or play along. It seems that some of them were
particularly desperate and were willing to harm interoperability.
