ObjectRemoved event may not be fired

[mcdonc]

If someone subscribes to an object removed event with a particular context but the object is removed indirectly (by perhaps deleting a folder in which it lives), the event will not be fired.

The cost of firing all those events is too high to make everyone pay. Applications which need this behavior should register a "re-broadcasting" subscriber, which converts the original event to a set of events, one each for the transitive closure of its items.

Agreed. It just needs to be documented well I think.

This is basically a documentation task that should explain that to catch all remove events, you'll have to register a subscriber for ObjectWillBeRemoved without any context (so it will be fired whenver any object is deleted) and resolve all oids in event.removed_oids.
