This is of course an astute argument. There are other consequences of this
when it comes to the Entity=Identity+Value case...
As it is now, I could load a Vehicle entity, be seen and accessed only as a
Vehicle, although it contains the full state of the Bus. But with the
E=I+V, that is no longer possible as I imagine the implementation.

Need some more thought on that.
