As long as that is the goal.. otherwise, I'd be overjoyed if I can rip nesting support out of the cpu-controller.. that stuff is such a pain. Then again, I don't think the container people like this proposal -- they were the ones pushing for full hierarchy back when. Another way there is simply deprecating and removing all non-hierarchical controllers (and not adding any more while we're at it).
