* It is tough to contribute to a project that doesn't use a formatter, * It is extra hard to contribute to a project which has configured the formatter, but ignores it for some files * Code formatting makes it harder to hide obscure / weird bugs by accident or on purpose, Let's rip the bandaid off? Note that PRs currently in flight should be able to be merged relatively easily by applying `clang-format` to their tip prior to merge.
