That makes sense, if the structure of your queries is largely static per commit of your codebase. You'd probably get more benefit out of a tool like this by running it as part of a CI pipeline, since that's the best time to test code changes including new queries. But then the challenge becomes simulating user activity and traffic levels during the CI pipeline. That's a solvable problem, but it's not as easy as just observing the real traffic in your prod network.
