We don't use it anymore, and it is not useful for static analysis (you only need to implement a subset of the methods to support all comparisons) nor at runtime (every object implements all of the __xx__ methods, but most return NotImplemented, meaning that isinstance(anything, Comparable) was always true even for things that were not comparable, like regular old object().
