I think I like this better expressed as a linter than a code reviewer. Maybe it doesn't sell as well. But giving this to devs to help them make better PRs and have more confidence in approval? Good. Skipping code review? Bad.

In my experience, most "issues" in code review are not technical errors, they are business logic errors, which there is most of the time not even enough context in the code to know what the right answer is. It is in a PM or Sales Person's head.
