Isn’t it just the MTI suites listed in s8.1?

Also, I added a comment in github requesting that we add a permanent note to the registry to alert folks looking there for the Recommended Yes/No marking.

IANA [SHALL add/has added] the following to the following to the TLS Cipher Suite Registry:

NOTE
      Cipher suites marked as "Yes" are the MTI TLS 1.3 cipher suites
      in the RFC 2119-sense (See Section 8.1 of [THISRFC]) and can be
      updated later. Algorithms marked as "No" are not; cipher suites
      marked "No" range from "good" to "bad" from a cryptographic
      standpoint.

Maybe we should also add that cipher suites marked “No” can later be marked as “Yes” later?
