Surely if you have an object graph where everything is saved by
pointer you want to track those cases as well?

Tracking in the above loop wouldn't help you if those pointers pointed
to stack objects, because, for that other part of the program to be
legal, the pointers would have to point to stack objects other than
the ones in the loop, which have all been destroyed by that point.
