We need this to handle cases like List<T> --> List<T extends @ReadOnly
Object>, right? Actually, now that I think of it, NonNull's @Default
implementation (which I've been really meaning to move to the
framework) could be trivially extended to support a
@DefaultTypeQualifier. If nobody minds me picking it up, I can do it
Monday afternoon after the ABB talk.
