Do you assume there is but 1 single session blocking the waiter?

False in cases where some N number of sessions are all holding less
invasive locks and you are pending on a heavier one.

To wit; share locks granted and an exclusive locker pending.

The question in regards to whether it's possible to  log more info
here in any case  isn't something I can answer personally.
