should we have a check for this?

Or a way to plumb it into the normal formatters we run

In some way, I'd love CI to just auto-format, re-stage and commit any touched file. Repeating CI runs bc of formatting seems a bit like a waste of time.

Footnotes

1. 1268 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on develop (873a7fb) during the generation of this report, so cb42321 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
