Different approaches were proposed:

 * CR from userspace only : we know it is not possible to fully support
the CR with this approach.

 * CR from the kernel space : the CR is monolithic and is very intrusive
in the different kernel subsystems and their interactions make the
maintenance very complicate for the owner of the subsystem. This is why
this approach has been nacked from the community.

 * a hybrid CR where the userspace collects CR information exported from
the kernel. IHMO, this approach is the better in terms of maintenance
and flexibility.

The latter is for the moment investigated by the containers@ community
and AFAIK this approach has a better chance to be accepted but there is
still a lot of work to do.
