TBH I think the text of the PEP could be much improved -- for example it should use motivating examples from real code, not artificial examples to show edge cases of the semantics.
At this point I don't think that more people expressing an opinion one way or another are going to make a difference. Nobody whose vote matters is going to be convinced either way.
