Does this mean we are dropping support for Python 3.7? If so, we might want to update the Python installation page in the docs: https://breakthrough-energy.github.io/docs/user/python_guide.html

Good point. We stop supporting 3.7 to follow what we do in other public packages.

I'm not an admin on this repo but looks like we need to update the required checks to remove 3.7, and possibly add 3.10.
