I feel we have reached an impasse and we must agree to disagree.

I believe we are each entitled to our own opinions. ;-)

I think it will be interesting to see what happens as more and more
domains adopt DMARC, including those that use p=reject. Especially with
some of governmental institutions purportedly being mandated to use
DMARC. - IMHO, DMARC is going to eventually become the new norm.
I also wonder what ARC is going to do to this paradigm.
