Credit for making left option groups higher precedence goes to Nick Coghlan. (Conversation in person at PyCon US 2013.)
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.
