[Python-ideas] Re: Dataclasses, keyword args, and inheritance

You're right, the goal of my PR is not to allow specifying keyword-only (or positional-only) `__init__` parameters, but rather the goal is to allow child classes to be defined with non-defaulted fields (with defaulted fields in parent classes). Keyword-only parameters is simply an implementation detail. I don't know about positional-only parameters, but a more fleshed-out solution would do something similar to `attrs` (as linked above) where the fields can be specified as keyword-only, which then allows non-defaulted fields in child classes as a side-effect.
