One major comment:

1. There is (and has always been) a semantic hole in ICE restart with
Jingle, because transport-info is a unilateral message, unlike SDP
offer/answer which is transactional.

Specifically, there's no way for a Jingle endpoint to know for certain which
generation of its local candidates should be matched with a set of
candidates received in a transport-info message.

Perhaps some sort of remote-generation attribute is necessary for candidates
sent in response to a peer's candidates?
