And other rt aware applications like cd burning.

(It is on sunrise, but only ~x86) Cgroup is a useful feature for big companies large scale servers, but for an audio-pro workstation, we just don't need it. Even if installed, it is possible to completely disable it in its configuration, and as long it doesn't make like udev, a good piece of software that is almost impossible to remove, and very difficult and time consuming to configure for a non technical user, I just don't care of it.
