TBH, ! is the perfect choise when the arg is of type bool. As PHP CS Fixer is not static analyser, it cannot know the type.

With this said, I belive this PR/feature is not wanted in the main repo, it is job for static analyser like https://github.com/phpstan/phpstan-strict-rules which will warn about ! when not applied strictly on bool only.

Agree with the previous statement.
It's too blind-decision to apply this rule, it should be done with extra care and I do not see it as part of main repository. Yet, I can understand the value to run it as one-timer, review and adjust everything manually, and then rely on stan to not introduce new issues. For that, please move this feature into custom rule
