Please no. DMARC is great for 1:1 direct email (from:me, to:you).
Anything other than p=3Dnone fails miserably once the scope is expanded.
Let me give you examples of things that would fail miserably under
your suggestion above:
1) This list
2) The recent, heavily forwarded and reflected, Cisco PSIRT notices.
NANOG is not the place to debate this, nor is it the place to advocate
self inflicted harm.
