Can you elaborate on which interface do you envision to make it work?
They will clearly be mounted in the same hierarchy, or as said
alternatively, comounted.

If you can turn them on/off on a per-subtree basis, which interface

Would a pair of cgroup core files like available_controllers and
current_controllers are a lot of drivers do, suffice?
