That is, the fact that Python 2 is not officially supported any more, and at maximum you'll see some fixes for most egregious security holes, is not something you considered back then?
I knew about the security risk, but I wasn't aware of how many quality of life and performance improvements we could use in the new version. And I also learned that some people enjoy researching/debugging the interpreter, whereas I originally thought the refactor would be a chore that hurt morale.
