The last time I touched a large Py2 project was in 2018 when I ported it to Py3. So, I have 18 years of Py2, probably 6 years of overlap, and 7 years of pure Py3. That means I still have a lot more Py2 than Py3 time.

Buuuttt, I'm so over the transition. It’s ancient now and I agree that we can stop fretting about it.
