You don't get it.

In the new world order only ONE process will be able to create/modify cgroups. That's going to be a kernel requirement.

This in turn requires cgroups management daemon to be constantly active.

only for the short term until they figure out how to allow for wider access. (and even then the old way will remain for compatibility for a while)

It also would't the only time some kernel developers have said that there was going to be a kernel requirement that they later back away from before enforcing it.

so it's very possible that there will never be a kernel release that will require only having one process manage cgroups

I haven't seen any indications of that.

And that's actually my sticking point with cgroups - I think that cgroups nesting and delegation is a must.

Yeah, sure. Without any new features.
