Hi Brian,
Thanks for your review! Please see inline.

Perhaps a topic for an IETF chairs lunch presentation?
I have to admit that I did not know about 6982 (now obsoleted by 7942). My
suggestion would to not collect that information for this draft at this point
of time, as it could take some time.

I can modify the address in the example, from IPv4 to v6.
Minor issue: (almost a nit)

SCTP supports multiple SCTP streams over a single association, and you can
still use that with 'TCP/DTLS/SCTP'. E.g, the WebRTC Data Channel protocol uses
two streams to realize a data channel.
I could modify the first sentence as following:
"NOTE: Due to the characteristics of TCP, while multiple SCTP streams
can still be used, usage of 'TCP/DTLS/SCTP' will always force...."

Correct. Will be fixed.

I'll fix that. I will use single quotes.
