The point of black is that you run it on the same codebase with the same parameters.

Prettier works the exact same way and does have --use-tabs as a parameter. Nobody died. No codebase ended up with mixed tabs and spaces from it. Codebases either do --use-tabs or don't.

Like I said, there are a lot of reasons to allow for this. For one thing, tabs are an accessibility feature, but also it's impossible to use Black in an environment that prefers tabs.

Whereas there's no such thing as "an environment that prefers exactly two spaces after every comma inside tuples", thus you don't need an option for this.
