This feature allows to deprecate ObjectStore.startTrackingNewObjects() and ObjectStore.unregisterNewObjects() and also optimize some ObjectDiff operations, resulting in fewer map lookups.

not sure if this would be a smart default strategy for the client in an ROP situation, as there is no underlying snapshot cache and swapping out previously resolved objects will result in extra db trips
