I understand the position regarding git contributions, but I am trying to get the point across that formatting code to a standard is a more general desire than just git contributions. It is a broad desire/requirement that should be considered. Rather than making processes git-contribution-specific, providing a more general solution that git contributors can use is more effective. I don't understand why this matters to the proposal, though. My experience with projects adopting code-formatting is that there are always some people who just don't use it (e.g. because they use a different IDE that doesn't integrate with it, or they never bother installing the extra tool, etc.). Such users run the risk of having automated CI jobs flag their code with a problem, and then they have to go back and fix it, but it's still a net win because reviewers don't have to spend time catching those problems, and the original folks would have had to fix their code anyway. In fact, in some projects, I've been one of those users and having the project use a code formatter that I didn't want to bother to set up and run didn't negatively impact me at all. Whether or not we have an automatic formatter, you're still responsible to fix your code to match the project's guidelines. I don't think that becomes any harder, because if we have an automatic formatter, the _most_ that changes is there's a flag day where the style is adjusted slightly. After that point, all you have to do is the same as today: look at the surrounding code to see the format and follow it. So, from what I can see, you lose nothing from this proposal if it is implemented.
