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

While I support the TLS version requirements changes that this document is 
making,
I seem to be failing to find the discussion/explanation of why this document is 
needed in
this format, as opposed to the changes being included as part of the updates in
draft-ietf-tls-oldversions-deprecate.


Also, I have some comments on the current text.

Didn't a late review comment to the last-call on the -03 suggest to have
the requirements here include "follow BCP 195" and get a positive
response from an author?  I don't see that change present in the -04.
(A similar change was suggested nearly a year ago for the -01, in
https://mailarchive.ietf.org/arch/msg/uta/6ZHi1RlE2CW3eLMub2HLXaiK8dY ,
but received no response.)

Section 2

Please use the normal BCP 14 boilerplate from RFC 8174.

Section 3

   OLD:

   In Section 4.1, the text should be revised from: "It is RECOMMENDED
   that new users be required to use TLS version 1.1 or greater from the
   start.  However, an MSP may find it necessary to make exceptions to
   accommodate some legacy systems that support only earlier versions of
   TLS or only cleartext."

   NEW:

   "It is RECOMMENDED that new users be required to use TLS version 1.2

There seems to be a mismatch regarding the presence of the "In Section
4.1, the text should be revised from" text.
