I think the answers are really implementation dependant.

For the first question, I would say if the PSB is refering to the RSB, at
minimum, the reference should be removed.

As to the ingress node's behavior, it should do something:-). Leaving the
Path refreshes indefinitely without receiving the Resv seems to be wasting
resources, unless there are some reasons to do so.

Hope this helps.
