The overhead of adding what are effectively unused attributes to a

what sense you're wanting to "simplify the object graph"? What
problem is there with adding the attributes to just those entities
that need them?
The original issue is that I was adding three keys to the base
class, when
most of the subclasses only needed to use two of them.
Just to clarify, do you mean base class or base entity?
