Only the first patch actually fixes a bug (very small memory leak during system tear down, so it's not even a critical bug). This could be added to stable. Patches 2 and 3 aren't fixes, they're desired behavioral changes to the feature. An interface being confusing doesn't mean it's broken. ~Gregory
