There was a problem hiding this comment.
Just to clarify (might be worth a comment): If we ever get into the recursive call situation, this effectively ignores anything in the compiler generate type (as if it's empty) -> for example suppressions would not work.
I think it's perfectly OK as a behavior, but might be worth a comment to make it clear it was an intentional behavioral choice.
