COMMENT:
----------------------------------------------------------------------

- 3.2.2:

I think it would be helpful to give some more guidance about the
“timeout” period. That is, when does it start, does it reset when a new
query is sent, etc? This is somewhat implied by the term “idle”, but it
would be better to be explicit.

-3.3.2:
I understand from later in the draft that the  OPT RR in a query does not
necessarily need to have include edns-tcp-keepalive for the server to
include it in the response.  A careless reader might easily miss that
distinction. It would be helpful to emphasize it here.

=== Editorial===
- Abstract:
The abstract is rather long. The first paragraph might be better left to
the introduction section.

- 1:
The introduction sort of buries the lede. The idea that clients and
servers need to manage idle connections is not mentioned until paragraphs
8 and 9. That's the whole point of the document.
