For the record, the requirement for a regression test is not any reflection on how good or obvious a fix is, or how silly the original error was.

I think it’s OK for us to take this change that has no effect with any current configurations and is useful to Google in your work with newer fancier versions of Skia. But in the future, change log should explain why there is no test when you propose a change without a test.
