We have special logic in the repo tooling that allows rfw to opt some files out of autoformatting. That dates to when flutter/flutter wasn't autoformatted because Hixie didn't think the autoformatter did a good enough job with Flutter code, and so he didn't want it enforced on rfw.

Now that flutter/flutter uses autoformatting everywhere, I think we should remove the opt-out logic, and autoformat those files. It's not quite that easy though, because there are annotations used by custom logic in the coverage regression detector in rfw's custom_tests.sh, and the formatter moves some of those comments in a way that makes the script think coverage has regressed. We'll need to revisit the logic of that coverage detection.
