If I were in that situation, I would make a reasonable effort to keep scripts as polyglots: Make sure they both run in Python 2 and in Python 3. In my experience, doing so is pretty easy to do when writing new code from scratch with Python 3 compatibility in mind. The “no one is maintaining Python 2” issue is an example of open source economics in action: Everyone wants Python2 to be maintained, but no one is stepping up to plate to pay for it to be maintained, so it’s not getting maintained.
