Another daemon for managing control groups

No. Because that is not what is happening.

Cgroups is about managing resources of processes in a hierarchical/grouped manner from what I can tell. Linux/Unix processes are already arranged in a hierarchical manner due to the parent child process. The parent process is PID 1, which is the Init.

Makes sense to me that you'd want to be able to manage things from the top down instead of having a entire separate process you have reprogram your applications deal with via dbus.
