Well, when we figure out a security model that works for that and can
be implemented in the kernel then lets add the new cdev.
But that is *explicitly* not what Jarkko is doing, no reason to jump
the gun.

Right, some future new cdev would only support ioctl and only the RM
path, but for priv use having both concurrently available makes sense
as a userspace broker producing a full RM will need to using both paths.
