Hi all! To clarify, my draft I linked to (and future profiles) are instantiations of the CNSA 2.0 advisory and FAQ as it applies to specific protocols relevant to NSS; specifically, the drafts document how we expect vendors to configure protocols in a CNSA 2.0 compliant way.

That's ML-KEM-1024 and ML-DSA-87 only. It would be better if that statement were in the official CNSA document [1], such as a FAQ or something, and not in an IETF document submitted by an individual. For example in the CNSA 2.0 FAQ [2] there is a section on “Hybrids” in the which gives a subtly different opinion. Taken together, my answer to Andrey is “it seems to, yes” Perhaps we can get official clarification?
