I'd like to request a new option to the `dataclasses.dataclass` decorator to make the `__init__` keyword-only. The two use-cases I have in mind are: (1) Using as a dataclass big-bag-of-config. In this scenario, forcing the user to specify the keywords is a lot nicer than passing in a dozen positional parameters. (2) Having kwarg-only parameters means that inheritance and default parameters play nicely with each other again instead of raising a TypeError.
