> Yes. I have lost count of the number of PRs that have come to me where the developer added random blank lines and deleted others from code that was not even in the file they were supposed to be working in.

That’s not a great example of lack of care, of you use code formatters then this can happen very easily and be overlooked in a big change. It’s also really low stakes, I’m frankly concerned that you care so much about this that you’d label a dev careless over it. I’d label someone careless who didn’t test every branch of their code and left a nil pointer error or something, but missing formatter changes seems like a very human mistake for someone who was still careful about the actual code they wrote.
