Winning a bet about "six", the Python 2 compatibility shim

> Here are the top packages that still depend on six:

Curious. `python-dateutil`'s dependency appears to be unconditional, but it also gets more downloads than `six` does. It's as if there are CI systems out there that can cache `six`, but not `python-dateutil`.

I also have to wonder who the holdouts are who demanded an update to `python-dateutil` in 2024 (as well as one in 2021) that still supports 2.7, and who can't be satisfied with the pre-sunset versions.
