We have two different kinds of @RequiresOptIn annotations in our library.
1. Annotations for new experimental API that might change.
2. Annotations for API that is easy to use incorrectly.
Which AnnotationRetention should be used in each case? (BINARY or RUNTIME, SOURCE isn't allowed)

Official libraries usually just use BINARY for all the experimental annotations, even though nobody scans them through reflection.
