Ups, indeed, totally missed it. Removed it from https://github.com/mariocj89/peps/blob/pep-pos-only/pep-9999.rst

 Actually Argument Clinic has always given left option groups higher precedence. This theoretically allows Argument Clinic to elegantly support the range builtin as "range(\[start,\] stop, \[step\])", although nobody has bothered to actually convert range() to Clinic. (Which is reasonable--I don't think there's any reason to bother.)

Anyway, this acknowledgement is the only mention of "option groups" in the document. Perhaps this was in reference to the now-abandoned idea of adding "option groups" to the language? If so, this acknowledgement should probably be removed too.
