I'd just as soon leave the entire thing out of stable backports.

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.
