You missed my point.  The IETF declared NATs heretical and as a result, a zillion people did it in a zillion different ways, creating a huge mess.  Lots of people are implementing sending/receiving DNS queries/responses over HTTPS. DoH simply codifies one way of doing it so that network managers, software developers, etc., have a chance to develop management systems for it.

Then force the folks on your network to install a cert so you can filter out DoH.  Contrary to your assertion, I doubt netflow will let you discriminate between good and evil. You have to have visibility to do that.

Too ostrich-like.
