The documentation for the VisibleForTesting annotation suggests that the analyzer will provide feedback if "the annotation is associated with a declaration not in the 'lib' folder of a package or the declaration is referenced outside of its defining library or a library which is in the 'test' folder of the defining package (

)." The analyzer does not seem to provide any feedback around this annotation. Currently the annotation is great for documentation purposes, but it would be even better if the analyzer caught the circumstances above and provided a warning. Are there any plans to do this?
