On the contrary, as a senior developer you should be able to look at and see the team-wide benefits of consistency. You don't have to handhold new junior devs to learn the style, you don't need to watch their PRs to see if they're being consistent, and you don't need to argue with other senior devs about whether something should be on a single line or not. You just let the automatic formatter do its thing.

Being a senior eng isn't about always knowing what's right, it's about knowing how to keep the team moving efficiently.
