> the default width should be at least 120 characters, I mean we're in 2022 after all
Even in 2022, some people don't have wide external monitors, sometimes like to view two files (or a diff) side-by-side, or need to use GitHub/BitBucket/etc. code viewer pages. Also, it's still difficult for humans to read long lines.
Agreed. It's really nice to be able to have two files side-by-side (or a file plus a shell) without having tiny font. I still do the overwhelming majority of my work on a laptop--maybe I'd feel differently with one or more 27" 4K monitors, but even then I don't think a code formatter should make these kinds of assumptions.
