Our (ANIMA) document already has TLS 1.3 as a SHOULD (and the ancedent document 
from
2021 said the same thing).   I was asked to make it a MUST, because 
uta-require-tls13.

Vendors violate MUSTs all the time; customers can use RFCs as big hammers to
insist.  It really does happen.

But, MUST do TLS 1.3 implies (to me), do *NOT* (refuse to) do TLS 1.2.
The only way to allow (MAY) TLS 1.2, is for TLS 1.3 to be SHOULD.
