I think we're in a chicken-egg situation (partially) where some kinds of
"DNS resolver operators" (e.g. ISPs) have only rarely deployed much of
this stuff, especially transport encryption, and they might like to get
inspired by at least some IETF-blessed advice, even if it won't be
perfect yet.  Example:
https://github.com/Encrypted-DNS-Deployment-Initiative/Workstreams/issues/3

I also hope for that.  Having touched this initiative I linked above -
it seems mostly driven by ISPs who are trying to figure out operational
BCP for DNS encryption.
