I enthusiastically endorse John's proposal for policy discovery.
PSL replacement using DNS Flags
This proposal specifies a resource record that can be used to distinguish
between PSL names and organization-controlled names. The design also
permits fine-tuning of organization-controlled names to obstruct misuse of
those names.

IMHO, that design has the same flaw of SPF, of requiring an organization to
define RRs for almost every host. DMARC overcame that hurdle using the PSL.
None of that is needed for DMARC.
Still, it could be possible to specify policy discovery so that if one day
something like Doug's idea, or like Dbound, were going to be available, even
partially, then it could be applicable without requiring a new spec. As long
as there's semantic equivalence, that is.
