I'm with you; since dataclasses were introduced, namedtuple has not see any use from me, though none of my uses have demanded ultra-high efficiency either.
I wonder how many users are currently relying on namedtuple __getitem__ semantics though. that's functionality dataclasses do not (currently) have. Random thought I don't know the answer to: Any reason __slots__ can't be used on a dataclass to improve efficiency?
