Thank you for the work put into this document.

Please find below some non-blocking COMMENT points (but replies would be
appreciated even if only for my own education), and some nits.

Special thanks to Suzanne Woolf for the shepherd's write-up about the WG
consensus.

Thank you also to Ron Bonica for the shortest (1 line) but positive review for
the Internet directorate:

I hope that this helps to improve the document,

== COMMENTS ==

I would have expected a little more about anycast DNS servers as TCP is
probably a no-go for those servers. I see only one mention of anycast in the
whole document.

-- Section 2.3 --
To be honest, I smiled when reading "For example, as of 2014, DNS over TCP" in
2021 ;-)

-- Section 2.4 --
The qualitative approach about IPv6 fragmentation makes me wonder about the
sources of this paragraph.

Still about IPv6 fragmentation, while "hence is unable to fragment and re-send
anyway" is most probably correct, the originating host should populate its Path
MTU cache for the destination. So, it is not that bad.

== NITS ==

-- Section 3 --
While I appreciate 2nd degree, I wonder whether "serious" should really be part
of "Furthermore, there has been serious research"

-- Section 4.4 --
Should the DoT acronym be used ?
