Thanks for the reply, but FWIW, I don't have a clue what point you
intended to make?  I looked at that CIRA page twice, and it is simply
a DoH/DoT forwarder.  Absolutely nothing in that release mentions any
change in DNS protocol.

DoH/DoT covers only one hop: the end user to the recursive resolver.
Beyond that one hop is good old-fashioned unencrypted DNS.  By using
DoH/DoT, whether in your own stub resolver or in a [future] BIND, you
are using that DoH/DoT server as your forwarder.

(Harald, please feel free to ignore Reply-To if you are unable to
post to the list.  Thanks.)
