The Apple Demo, which is very thorough, doesn't "prune" persistent history?
And the Forum Thread seems to suggest that persistent history is integral to how NSPersistentCloudKitContainer works.
Are we supposed to explicitly prune persistent history ourselves or is it handled for us by NSPersistentCloudKitContainer?
