both options have their pros and cons. if you utilize some form of ratcheting[1], you can sneak it in without your team knowing.. but all of your PRs for the foreseeable future will have a ton of reformatting screwing with your git blame. if you do it all at once, someone will have to sort out conflicts, but you can utilize `blame.ignoreRevsFile`[2] so that your history remains useful
