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).
