Or perhaps we could have an officially blessed way to give tools a hint as to what the real signature is.

class Child(Parent): @signature_hint(Parent.method) def method(self, **kwargs): pass

I was planning to submit a PEP to support a __signature__ attribute (without the _hint) in inspect.signature(), see PEP 576 and PEP 579 for some context. The reason is very different from what is suggested here: to allow implementing custom function-like classes that inspect should treat as functions.
