That can be an automated CI check that runs the new tests with the non-test files reverted though.

It can be! And maybe even should be. But I've never seen it.

A great idea, though; when we finally get automated testing in CI, I'll certainly suggest it :)

That wouldn't necessarily compile though, eg if the fix involved changing a function signature or adding new functions.
