It would be a disaster if the base class's slot descriptors would be broken by that though, so the implementation of slot descriptors would have to become more complicated. (It's worth understanding how __slots__ works. the interpreter first finds the slot on the class and then calls its __get__ method to retrieve the actual value from the instance. Each slot descriptor, in the current implementation, knows the offset of its slot within the instance.
