> Currently, resource requests for the same container and locality are expected to all be the same size.
> While it it doesn't look like it's needed for apps currently, and can be circumvented by specifying different priorities if absolutely necessary, it seems to me that the ability to request containers with different resource requirements at the same priority level should be there for the future and for completeness sake.
