I don't think so.  We will need @RootQualifier (already there!) to do  
this.  List<T> should be List<T extends @RootAnnotation Object> rather  
than List<T extends @DefaultAnnotation Object>. In the case of IGJ for  
example, the default annotation is always mutable, but the root is  
ReadOnly.

I assume that this may be different for NonNull, and List<T> in a  
method signiture might be for List<T extends @NonNull Object> rather  
than List<T extends @Nullable Object>.

You can.  The AnnotationRelations already provides the root  
annotation.  We can discuss it a bit more later.
