I have a concern with this:

The draft draft-tls-westerbaan-xyber768d00-00 references
draft-cfrg-schwabe-kyber-01, which has a number of annoying mistakes,
since fixed in editor's copy.

And then, the correct reference for X25519 is probably RFC7748 instead
of RFC8037...


Really quick and dirty way to fix this would be to publish editor's
copy as draft-cfrg-schwabe-kyber-02 (or if CFRG adapts quickly, the
RG-00), and then publish draft-tls-westerbaan-xyber768d00-01, fixing
the references.
