You use terms such as client and resolver but at times it is not clear if you are referring to the OS stub, a third party stub, caching resolver, application or browser. Maybe using terms from your terminology draft would help.

The client is always "the thing emitting DNS queries"; the draft doesn't assume what other role (OS, browser, webapp, ...) the client plays. This is always going to be a problem for us with DoH, and I agree that we can have careful wording around it.
