That is the intention.

Ingress router depends on downstream routers' PathErr or ResvTear messages
to find out any connectivity problems. Those are standard RSVP messages,
so no extra procedures/protocols required to make it work.

No.

It does. However, unlike link failures, node failures are more difficult
to detect in timely fashion.
