Review Comment:
@uranusjr Actually, I think the right way to handle the follow-up would be
to re-dispatch the callback with a fresh token. This would handle the case of a
worker dying after an exchange, not only the case of the server's response to
the worker being lost for whatever reason.
Since we've agreed this PR is in the right shape to be a 3.4.1 stopgap, I'll
resolve this thread, and we can move follow-up conversations into the issue
#76735
