Okay, did a review of draft-ietf-tls-curve25519 (since it still
doesn't seem to have been WGLC'd):


Major issues:
-------------

None

Minor issues:
-------------

- The functions got renamed in cfrg spec (which seems to just
  be concluding IESG review[1]).
- Some references look pretty obsolete (e.g. cfrg-curves from
  January?).
- Maybe add an example key exchanges (just copy test vectors
  out of cfrg-curves and rename things a bit to fit the way
  values are used in TLS)?


[1] In chacha20-poly1305 document processing, IESG review
was followed by sending the spec to the RFC editor.
