I guess because the interface only requires the methods to be
implemented, but allows them to be implemented in a base class as well
as the class itself.

Maybe Object itself as well?
That way functions can accept any object (whether referenced by class or
interface) as an IObject.
Though I would prefer it if all interface references would just be
implicitly convertible to Object. Java does this, IIRC.
