Then there is SPF. A fare portion of the reason why the SPF record failed, despite it being architectually cleaner than using TXT records, is that some nameservers gave bad responses to SPF queries.
Hi Mark, I'm going to stop you there. The SPF record type failed because resolvers can't pass requests between clients and authoritative servers unless they can parse them. New DNS record types essentially require a universal software upgrade before they work. And universal software upgrades do not happen well or in anything approaching a timely manner. The next new DNS record type will fail for the same reason. And the one after that. TXT is the DNS record type that's extensible without a software upgrade. Like it or lump it.
