This draft is ready for publication from a transport point of view. I have minor nits / suggestions:

(1) References to QUIC imply that work is underway to build DNS over QUIC; while this has been suggested, there is to my knowledge no ongoing specification or implementation of such an application. There should be some additional text pointing out this context where QUIC is first mentioned.

(2) The references have some typos (e.g. [pitfalls-of-dns-encrption]) and are occasionally oddly named (e.g. [firefox] for a Mozilla announcement about DoH); suggest reviewing these.
