Ah I see the disconnect, I think the underlying piece I glossed over was the fact that dict objects and set objects rely on the same hashable property of objects. This is in part due to the "one way and only one way" rule of thumb of Python's language design.

For me, talking about how dicts handle hashing keys and sets hashing members are equivalent in the context of the Python language.

Given that context I was saying changing the "hashable" nature of default objects would be counter-intuitive as the new behavior would be in contrast to the expected behavior of sets and/or immutable equal types in dict keys.
