> A formatter is pretty essential when working in a team.

I worked on a team without a formatter for more than 5 years. I'm certain many people have done the same. "Essential" is overselling.

I think at this point I would consider a formatter essential for working with a team. It helps make code style opinionated and fixed and I have no surprises when reading code. No one doing weird formatting to align random things. Any formatting tool that allows for pages upon pages of options is simply not something I want to deal with. Something like black, gofmt and prettier is vital

Bike shedding. I say this as somebody who has written a once prominent JavaScript code beautifier. Automating code beautification is a nice to have. It becomes essential when developers cannot be bothered to focus on more important things because either more important things are too challenging for the given developers or because the given developers want to feel more important than their contributions/decisions are actually worth.

Auto formatting tools like prettier and black didn’t use to be essential but they’re quickly becoming essential. Just look at the growth curves for pip and npm installs. I for one feel like my editor is broken if it doesn’t auto format on save.
