Instead of requesting owners and maintainer separately, each with their own limit of 10 review requests, we now run this together. This unties the logic and allows easier refactoring. Also, it gives us a consistent threshold of when not to request reviews anymore, which I set to 15. Before, this could have been anything between 10 and 20, depending on how the reviewers distributed over owners and maintainers.
