I think this draft could use review from readers familiar with HTTP.  I
hope that people with knowledge of HTTP will help us to understand whether
this draft's recommendations would result in a significant increase in user
privacy.

For the draft's authors, I have a question: does this draft's "privacy
threat model" include a DOH server that uses active measures to
differentiate clients?  Or is it scoped only to passive discrimination
between different client implementations?

As for other issues, I think the draft might need to consider header
order.  I also couldn't find an easy list of mandatory headers in RFC 7540,
so that list might be worth repeating.
