A few things jumped out about IANA registries. The first is a silly
process question that might be really ugly to address now (and require
the IESG)

Shouldn't the IANA registry here be made by the
draft-ietf-tls-keylogfile? That would make more sense.

And we don't seem to tell IANA to add the new labels defined here. To
my mind that needs to happen lest IANA not notice they were supposed
to do something we didn't explicitly say in the right format
(deservedly so! We should be really explicit to make their lives and
ours easy).

Substantive issues:

Section 4 I don't think is right. I think we want outer in all cases
because that's easier, There's lots of reasons a negotiation might
fail, and the interpreter of the data might not see this. In fact, how
does e.g. Wireshark know what matches the pcap if we use the
InnerClientHello random? I can see a process logging also logging the
secrets before knowing if success happened.

I hope these comments are useful.

Sincerely,
Watson Ladd
