I think the draft is generally very helpful in navigating the acronyms and
abbreviations associated with this space.

It should be pointed out that "Do53:  DNS over UDP or TCP as defined in
[RFC1035]..." is transmitted in the clear, even though I'm sure most
readers of this list know that.

This part seemed a bit off to me, although I admit I don't have good
alternate text.

Don't a lot of clients and servers already have userland versions of this
functionality, even prior to DoH etc? Sometimes they call getaddrinfo or
equivalent, but lots of them have their own cache policies etc. It is true
that they usually use the OS-supplied DNS servers by default, though.

thanks,
Rob
