Stephane, Thanks for the comments and sorry it’s taken me so long to respond. These comments made me entirely rethink what’s in the I-D. I was way too focused on maintaining alignment with draft-ietf-netconf-over-tls13 and that should not have been something to fixate on.

In thinking about what’s missing, I have come to realization that really only two things are: 1) A statement about what to do if an PCEPS implementation supports more than one version of TLS. I tend to think that if a connection can support a later version it should. 2) A statement about not supporting TLS 1.3’s early data. And, maybe some text about what early data is and why we’re saying anything about it at all. I think we can do that by adding two restrictions to those that are already listed in s3.4 Step 1 and a couple of notes. So, I thought what if we recast the entire draft to do exactly that. Let me know what you think about the following PR: https://github.com/ietf-wg-pce/draft-ietf-pce-pceps-tls13/pull/11 > Security considerations: > • I don’t see Security considerations of RFC8253 referred in the > section ? shouldn’t the draft build on top of it ? Is there any new > consideration compared to RFC8253 brought by TLS1.3? Yeah those ought to be there too.
