Gin module binding using annotatedWith and AsyncProvider

If I want to inject an instance of a specific class based on an annotation, I can do this in a Gin module:

bind(DiSecondary.class).annotatedWith(Special.class).to(DiSecondarySpecialImpl.class);

I also already have:

bind(DiSecondary.class).to(DiSecondaryImpl.class);

I can then retrieve the special instance into my DiMain (Composite wrapping a Panel) constructor with:

@Inject
public DiMain(@Special DiSecondary special) {
  add(special);
}

But, if I want to code-split DiSecondarySpecialImpl using AsyncProvider, the analogous approach does not work:

@Inject
public DiMainAsync(@Special final AsyncProvider<DiSecondary> diSecondaryProvider) {
  diSecondaryProvider.get(new AsyncCallback<DiSecondary>() {
    public void onFailure(Throwable caught) {}
    public void onSuccess(DiSecondary result) {   
      add(result);
    }
  });
}

I get a GWT compiler error.  If I remove the annotation, then, of course, I get the non-special implementation.

Am I being unreasonable to expect that the compiler could apply the annotation to the async provider for the base class instead of the base class itself?

Is there a different route that I can use to get the desired behavior (annotation-based selection of an alternate async loaded class)?
