Fact is, the scheduler does both these things, so there's absolutely no
reason for other controllers not to do so too. Its the only sensible
thing if you want hierarchy.
My utter disregard for cgroups comes from having to actually implement a
controller for them, its a frigging nightmare. The systemd retards
mandating all this nonsense for booting a machine is completely bonghit
inspired and hasn't made me feel any better about it.
