Whats the difference between SonarQube AI rules and others?

I wonder why SonarQube promotes special handling of AI generated code. Also reading the docs that I found, I do not really understand what difference it makes, to flag a project as using AI generated code or not. In the end you want the same code quality, no matter if AI generated or not, or?
Is this just marketing …bingo to have more “AI” in the product, or is there a real reason which I do not see yet?
