That’s not actually true. While dataclasses to most of its inspiration from attrs, there are many features of attrs that were deliberately not implemented in dataclasses, just so it could “fit” in the stdlib. Or maybe you mean the backport of dataclasses to 3.6 that is available on PyPI? That actually came after dataclasses was added to 3.7. Source: I wrote dataclasses.
