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:

(name := expression) makes code less uniform. It inserts more information into a place that is already heavily packed with information (logic tests).
