See#95065 (comment) by Serhiy. Quoting:

Turn positional-or-keyword parameters into positional-only parameters. A directive which means "the preceding positional-or-keyword parameters will be positional-only parameters in future".

In#95151, Argument Clinic learned how to deprecate positional use of parameters. In this issue, we propose to teach Argument Clinic how to deprecate keyword use of parameters.

Suggesting to use a similar syntax as the one introduced in#95151

func   a: object   / [from X.Y]

Meaninga will be positional-only from Python version X.Y. We can reuse parts of the code introduced in#95151 to implement this feature.
