Is there any user demand for heirarchy right now? I agree that we should
design the API to allow heirarchy, but unless there is a current need for it
I think we should not support actually creating heirarchies. In addition to
the reduction in code complexity, it will simplify the paradigm presented to
the users. I'm a firm believer in not giving users options they will never
use.
