Examining the difference in the reports sounds hard, especially if the
mail flows and remote operators' settings changed since p=none. As a
matter of fact, p=none lets a domain learn more about its mail flows,
since aggregate reports contain DKIM and SPF identifiers of mediators.
Is that good to know? Certainly, many operators prefer not to see any
failure in the reports thy receive. Hence p=quarantine; pct=0. Is
that /all/ operators, or are there any who would like to know about
indirect mail flows anyway?
IOW: should we support an option to get aggregate reports even if a
mediator munged From:?
