Couple of small things:

typo, Intro: "Users typically configure their DNS recursive resolvers with
through automatic configuration"

I don't get the "Do53" abbreviation, but I'll grab you and maybe you can
help me make sense of it (a very small thing considering you could have
said DoPotatoes or whatever).

Are there any outcomes you can see where IANA is compelled to delegate the
SUDNs here? Or where an authoritarian government might require resolvers to
collide, if that makes sense?

In privacy considerations the draft says, "can increase communication
privacy because of the TLS protection." I'm wondering if it makes sense to
say explicitly "confidentiality and integrity" in a parenthetical near

Thanks for this work, feel free to respond on-list if helpful!
