from the point of view of many operators and implementers (so, like dns
made easy, powerdns, and cloudflare from your example above) there is
almost certainly a disadvantage to interoperability and standardization
here, that being economic, in that as long as this feature remains
incompatible, a single vendor is likely to gain business via "lock in".
my reason for preferring a standardized way to do this is to make it
possible for a registrant to get primary name service from one vendor
and secondary name service from one or more others vendors.

i don't think it makes sense to question, inside the IETF, whether a
vendor-independent interoperable standard is desirable. we can ask
questions of the form "but is this good engineering?" or "is this the
best way to do it?" or even "what should the applicability statement
be?" but since the IETF's stated purpose is to promote interoperable
standards, if we want to argue about whether we need an interoperable
standard for this widely-used feature, we should move that thread to a
non-IETF forum where it would not be a nonsequitur.
