I have reviewed draft-ietf-kitten-tls-channel-bindings-for-tls13-01.

My only comment, besides a thank you, is this:

 - Section 1, first sentence
   
   | The channel binding types defined in [RFC5929] were found to be
   | vulnerable to the "triple handshake vulnerability" ...

   I believe that's specifically about tls-unique and
   tls-unique-for-telnet, but not tls-server-end-point.

   A slight rephrasing would be useful, as there is no need to give the
   wrong impression about tls-server-end-point.

Thanks,

Nico
