Useless dependency?

[frenzymadness]

I see that this project depends on future:

https://github.com/amperser/proselint/blob/fe368030357a8300f383f9e906c08c73317d2021/pyproject.toml#L21

but I cannot find any real usage of this library here. Why do I care about it? future will no longer work with Python 3.12 because imp module has been removed from stdlib and the situation will be even worse with 3.13 because the lib2to3 which is the core of the future will be removed from stdlib as well.
