Those who are following the discussion on oblivious DNS and oblivious DoH might be interested in a draft just posted:

https://www.ietf.org/archive/id/draft-thomson-http-oblivious-00.html

We're asking this to be dispatched in SECDISPATCH, so any thoughts you might have about venue should be taken up in this thread [1].

The goal is to provide a generic layer that can be used by things like Oblivious DoH.  DPRIVE might be interested in the applicability of the mechanism to an in-DNS-protocol design, or maybe might be interested in discussing some of the proposed differences in design approach with [2].

This doesn't (yet) include any substantive material on discovery of the various functions here, which might be of interest to ADD.  Some work on that is possible, but my personal view is that that would depend on getting clarity about requirements.
