Seems something is up with the Linux changes. Time to drill that one down...

Greetings. I was just wondering why to change type hints for list, dict, type to their deprecated alternatives in typing module? I honestly thought today it's common to migrate from typing.<type> to types itself as they now support subscripting.

Hey @norohind thanks for pointing that out.

I'll be honest, my brain was still operating under the older Python 3.8 typing system. I'll look into the newer typing system and see if we're making an accidental reversion instead of a forwarding of the system.

As I can't actually get a working Linux instance up right now, rolling back the linux config checks as they are failing the tests. Only going to work on things I can actually test right now.

Looks good re functionality, some small thing re readability in config/__init__.py though.
Additionally you're moving back to the deprecated Optional[] in two files.

Updated as indicated. Oldstyles replaced and documentation added in lieu of removal.
