me, too.

But single mount point just assumes "all necessary subsystems are mounter at once"
So,
    /cgroup/<subsys>/       #this cannot handle multiple subsyses.
    or 
    /cgroup/some_nick_name  #just depends on users.

Hmm. Making documentation to use the same mount point is not so bad. But in real
usage, cgroup's mount point seems case-by-case. 
If libcgroup or libvirt shows some policy, it's good for users.

  /cgroup/<libcgroup's grouping nick name>/ ...

or some.
