Starting development for Mesa 3.0 and following SPEC 0 we can drop Python 3.9 support and require Python 3.10 or higher for future development. This allows adopting more modern Python features and simplifies the testing and CI configurations. See the Python 3.10 release notes: https://docs.python.org/3/whatsnew/3.10.html The 2.3.x release series will keep supporting Python 3.9.
`X | Y` can now be used for type annotations, including making a variable optional with `X | None`

Good catch, added it. The reason I opened a new PR because the previous one didn't move forward and looked incomplete. This one is a fresh take without conflicts including all the typing changes that can be made automatically. |
We can do this now in Python 3.10!
