I feel like "from __past__" would have allowed projects to get to the point where they were "on Python 3" much sooner, though. The mentality would have been "we're on Python 3, and we have a long tail of cleanup to do excising from-past out of our codebase" rather than "we and our users are all still on Python 2 but we thiiiiink our code is mostly using constructs that are Python 3 safe. We get a green CI checkmark, anyway, but who really knows."
