I suppose we could leave pct=0 as a hint to forwarders to turn on their DMARC

Why doesn't seeing DMARC as seeing that it isn't p=none ought to suffice for
that?
Some lists operate the evasion hack, a.k.a. From: munging, only if the sender
has p=quarantine or p=reject, some do it unconditionally, some only if the mail
is outbound, some only if the receiver is mail.ru. Behavior doesn't seem to be
settled yet.
We should add a section on From: munging in the spec.
