I think your document would be a great blog post. I don't think it is very helpful as part of the standard documention, as it is more a collection of arbitrary facts about None than a coherent "big picture" document.
Thank you. That's nice. However, I think there is, or should be, more coherence than you're seeing.
Here's something I forgot to say. For standard documentation I was thinking The Python Tutorial. For example, the Brief Tour. https://docs.python.org/3/tutorial/stdlib.html https://docs.python.org/3/tutorial/stdlib2.html
That said, a blog post would be useful stepping stone, and the standard documentation later. (Know where your heading, take one step at a time.)
Once again, thank you for your comment.
