But it is recognized in the SIP community that it will be a long time
before all SIP user agents support ICE. I am not sure what timeline is
expected for SIP relays, B2BUAs, and the like.

There are, presumably, legacy gateways and B2BUAs for things like
SIP<->H.263 and SIP<->IAX. Those things might not support ICE yet, but
it might be fairly straightforward for them to add support for Jingle.
