I think the interface is a bit premature. The cpuset partition feature is
already pretty restrictive and makes it really clear that it's to isolate
the CPUs. I think it'd be better to just enable all the isolation features
by default. If there are valid use cases which can't be served without
disabling some isolation features, we can worry about adding the interface
at that point.
