This reads dismissive to me. I did read the PEP and followed the discussion on
python-dev. I referred to PEP 20 because it distills what's unique about the
value proposition of Python. It's our shared vocabulary.

Can you address the specific criticism I had? To paraphrase it without PEP 20
jargon:
