I believe I have collected sufficient attestations from the WG that a new proof 
is required for draft-ietf-tls-mlkem.


Can you explain why the synmmetric argument in your draft does not hold for 
hybrid key exchange?

I disagree and agree with John Mattsson about discussion, notably:

  *
- This concerns KEMs in general and is independent of draft-ietf-tls-mlkem, 
ML-KEM, and PQ.
  *
A proof in the symbolic model would be valuable, but not required, as there are 
already other proofs supporting the security of KEM use in TLS 1.3.
