Comment:

 Could you outline your threat model? (what do you want to protect from
 whom)
 (in a context of: most tor traffic is http/https)


 You need more than one semi-trusted resolver (we don't want to give _any_
 single entity all exit DNS traffic), we would need at least ~20.

 I prefer DNS-over-TLS over DNS-over-HTTPS.

 The problem is: even if you hide DNS content with encryption from a
 passive observer, they can still watch HTTP and TLS/SNI hostnames and get
 the same information.
