One of the main selling points of Prettier for a lot of people is that it is extremely opinionated and leaves very little formatting choices up to the user. If you respect user-introduced whitespace then the same code written by two different people can end up formatted differently, which is precisely the problem Prettier is trying to to solve.

I would argue the example posted above is still "consistent" because the rules Prettier follows for line breaks (and everything else) are consistent throughout the codebase. Things will be on one line until the line is too long or complex, and then it will break to multiple lines. The rules don't change depending on who was writing the code, what the code is, or any other factors. It may not be formatted exactly how you want, but that's kind of the whole point. It's formatted how Prettier wants, and that's the only option.
