I think this might be an overconcern. In normal
situations, cgroup delegation is strictly under the administrator's control.
Furthermore, if a user already has a delegated root, there are numerous
other ways they could potentially cause a DoS attack. Therefore, I believe
this doesn't need to be modified.
