The problem is not really about which behavior is "righter" but rather it's fairly likely that there are users / tools out there expecting the current behavior and they wouldn't be too happy to see the behavior flipping underneath them. One way forward would be implementing a knob in cpuset which makes it switch sbetween the old and new behaviors in the legacy hierarchy. It's yucky but doable if absoluately necessary, but what's the reason for you not being able to transition to the unified hierarchy (except for it being under the devel flag but I'm really taking that devel mask out in the next merge window)? The default hierarchy can happily co-exist with legacy hierarchies so you can just move over the cpuset part to it if you need it.
