That doesn't really apply here... Like I said, Python code is already much more uniform than most other programming languages. Unless somebody's formatting style is particularly ridiculous, their code should be just as readable as anybody else's, even if they put a space where it supposedly doesn't belong, or use too many/too few blank lines, or use the "wrong" way to split and indent a long list of function parameters. There is no productivity gain for others here. Maybe for languages like Javascript or C, but not Python. Almost all of it is just nitpicking.

(Of course you can make code less readable in other ways, e.g. by choosing undescriptive names, or weird idioms, but flake8/Black naturally don't address those issues.)
