There is roughly ~50 rules in code quality set https://github.com/rectorphp/rector-src/blob/main/src/Config/Level/CodeQualityLevel.php

So using extra high value, does not make sense (and gives false feeling the quality is much better now :))

->withCodeQualityLevel(200)

Adding warning about high level would avoid this confussion: #8984

Level methods are stepping stone to improve codebases step by step.
But once this process is finished, the whole set should be used instead 👍
