I still think rustfmt made a mistake by going with four spaces. It's basically inferior for everything except forcing everyone to use the same indentation width, which is actually a downside, since I constantly encounter two-space indent codebases that I can't read and also can't change to four spaces because it's not tabs. Also translating spaces to tabs visually is undecidable thanks to alignment, while the inverse is not true. Ugh.
