I don't have a problem saying that for a class to be used as a base class for a dataclass, its __slots__ must not be an iterator that's been exhausted. That doesn't seem like a very onerous requirement. I'm also not concerned about people using __slots__ to iterate over the fields, but I agree that a documentation note couldn't hurt. @ariebovenberg: go ahead and submit your PR. Thanks!
