If you do that, what do you use for post handshake TLS messages, such as
new session ticket messages?

This isn’t fully thought out, but the idea is that each such exchange has a
logical conclusion and streams termination could communicate that.

Rekeying isn’t tied to paths for the time being, but there could be a one
to many relation between keys and paths such that each path has exactly one
set of key pairs.

There could be ambiguity in ordering, which is mostly an issue with
serialising against the TLS interface in case you deal with multi-path
rekeying, I suppose - since I haven’t worked closely with that yet.
