I could see this being useful in similar scenarios as to why ruff adopted it, but I can't think of other tools that implement this pattern.
Also, I'm not sure if hukkin will have time to review or would approve, so take my feedback with a grain of salt!

I think there might be an error in this test if I understand it correctly:

| "--exit-non-zero-on-format", | ||

This new option should be mutually exclusive with --check (and maybe better document that both are CLI only because it doesn't make sense to configure these permanently in toml)
