Calling the migration from Python2 -> Python3 "Python3 Support" is disingenuous at best.

You don't have a choice. There's no going back. You shouldn't BE supporting Python2. If it breaks in Python2, then that's fine, because no one should be using it anymore.

Any project that hasn't switched (motioneye, calibre, etc) has had years to work on it. Frankly, it's embarrassing.
