DMARC lets a domain owner say "if mail with my name on it doesn't have these features, it's not from me." The org domain hack lets it say similar things about its subdomains which may or may not exist. But other than that, domains that do not exist do not have DMARC policies, and DMARC has nothing to say about them. Please stop trying to make it into a FUSSP. There are good reasons that a mail system might refuse mail from domains that don't have an MX, A, or AAAA, but they have notthing to do with DMARC.
