I am not a fan of splitting documents only for an abstract sense of
cleanliness. There needs to be justification of improved documentation
'cleanliness' and/or useful removal of fate-sharing -- if separate fates
are reasonably expected.
DMARC alignment validation is a basic, mechanical process that produces
a yes/no response. At that level, it's comparable to the nature of a
DKIM validation, except for the From: field domain.
DMARC "policy" is fundamentally different. It's not that its mechanism
isn't "mechanical" but that its semantics produce more semantic and
operational challenges.
I think that could reasonably make it worth strongly separating them
into two different documents, no matter has small one of the documents
might be.
