Is it possible to modify how run() is typed so the result isn't potentially None?

[red8888]

This is a semi ignore question, but I want to know if this is possible and if I could open a PR to fix.

This is kind of an annoy behavior:
def run(self, command: str, **kwargs: Any) -> Optional["Result"]:

It means I always have to check if its not None, but from what I understand the only case where it will return None is if disown is set to True right?

Is there a way to refactor so the response is always expected to return unless disown is set to true?

Maybe just a super simple class hierarchy where the base Runner class has everything but there are two children:
DisownedRunner and OwnedRunner?

And then DisownedRunner runner is the only one that is potentially None?

Thanks! I'm asking more what it would take to fix so I can open a PR more than just asking for this to be fixed, I'd like to contribute!
