I bet it will be tempting to extend it for other uses. Just like it was for me :). It looks just like another cpu_*map and stuff.
We could emulate isolcpu= boot option (the only visible user interface) via cpusets I suppose. But I'd rather not. Since we do not plan on supporting it I'd say lets get rid of it.
