What do you think about implementing this now? What should be the next step? Would it require a PEP?

Just lending support to the idea: this would be a fantastic addition to the dataclasses module and I for one would use it CONSTANTLY.

The style of coding I have become accustomed to relying upon (in the context of professional engineering calculations and analyses) has tended to favor kwarg-only arguments a majority of the time, for a variety of reasons. It's possible I'm creating problems for future me, but I don't think so. When using a good IDE or Jupyter, kwarg-only functions are far from a hassle to use, they are really a pleasure to use (and read).
