Hi @5chmidti and @HerrCai0907 any thoughts on the "Would it help if this was instead a checker option?"? Given the volume of false positives right now, I think skip by default, but can turn on if needed.

I updated the description to include the point of "we are currently seeing many false positives in test files, and it becomes harder for developers to spot such true positives, given the FP noise to filter through".
