http://python-notes.curiousefficiency.org/en/latest/python3/questions_and_answers.html
covers some of the questions Eric is asking (mostly from my PoV, but
Guido corrected my answer to the initial "Why was Python 3 made
incompatible with Python 2?" question shortly after I posted the first
version of it).

https://www.curiousefficiency.org/posts/2014/08/python-4000.html is a
more retrospective-y article that looks more at the implications for
Python 4.

For the "What actually happened?" info, probably the 3 main documents
to look at would be PEP 3000 (the process doc), PEP 3100 (accepted
changes that didn't get their own PEPs), and PEP 3099 (explicitly
rejected ideas that also didn't get their own PEPs).

Cheers,
Nick.
