I disagree on that though. By sticking to vanilla Black (no pun intended) you ensure that people joining your time will probably already be familiar with the style, you prevent strongly opinionated employees from pushing for changes in the linter config.
Black is opinionated, so it skips the debate entirely. We just use Black, not black with 120 characters lines, just Black.
To each their own I guess, but to me it just seems like pandora's box. Once you show that you are open to changes in the linting configuration, it makes the rules mutable and pretty much guarantees that at some point someone will say "how about we just change this one parameter in the linter", which will probably be agreed by the rest of the team, not because they actually agree but because they don't want to argue.
