Not necessarily - you could have both compiled in, and each would only worry about the resource management that they cared about - e.g. you could use the memory node isolation portion of cpusets (in conjunction with fake numa nodes/zones) for memory containment, but give every cpuset access to all CPUs and control CPU usage via the resource groups CPU controller.
The generic code would take care of details like container creation/destruction (with appropriate callbacks into cpuset and/or res_group code, tracking task membership of containers, etc.
