I believe that too. I also believe that the document will benefit from
reviews and comments.

Me too.

When I read the current draft, I found too issues that will hopefully be
fixed in the next revisions.

The first issue is the deployment model. I believe that a very common model
will be the connection by client hosts to a trusted recursive resolver. One
has to "read between the lines" of the current draft to find how the
considerations apply to this model. I wish we could have a more explicit
discussion of that scenario.

The other issue is the interaction with "firewall policies" in common use in
enterprise networks. These policies include making internal sites available
to hosts behind the firewall, but not outside it. They also commonly include
barring access to a variety of "not safe for work" domains. Encrypted
connections to a DNS server could traverse these firewalls, and bypass these
policy controls. The issue is documented in CERT Alert (TA15-240A),
"Controlling Outbound DNS Access,"
https://www.us-cert.gov/ncas/alerts/TA15-240A. We should address it.
