Just in case it wasn't clear from previous the exchanges, basic architecture designs like this are what makes things like delegation actually useful across all controllers. If we allow a descendant in the hierarchy to restrict waht its ancestors can do, it becomes really painful operationally. For now, I'd suggest just doing it at the first child level and move on unless there are clear use cases where nested partitions are useful, which I find unlikely given the nature of the operation - partitions don't really have anything to do with one another.
