One solution to improve backwards compatibility would be to duplicate some classes. For example, make a separate class for bound methods in extension types, which would be literally a duplicate of the existing types.MethodType class (possibly with a different name). In other words, a bound method of an extension type would work exactly the same way as an existing bound method but it would artificially be a different class for the benefit of non-duck-typing.
