My understanding is that by using Black you're saying I choose to not express my opinions about formatting aesthetics and delegate that decision to Black instead.
Which, as a longtime Go dev and now Rust dev, I love formatters that are opinionated. I don't always love what Gofmt or Rustfmt do, but I definitely like consistency that the community has in code style.
So I don't care what Black thinks - I care what, hopefully, everyone uses. Though, I could see a situation where formatting can be altered and the project has a format config. Meaning that while code fmt differs between projects, it would be consistent among all devs working on X projects.
I was initially grumpy about my org adopting black because I preferred single quotes, but the level of standardization is a huge win in my book. I never even think about my code style anymore, I just write it and then run black.
