So you would use:
FilterFactory ff = CommonFactoryFinder.getFilterFactory(new
Hints(Hints.LOOSE_BBOX, true));
Gt2BBOX box = (Gt2BBOX) ff.bbox(...);
where Gt2BBOX would be:
public interface Gt2BBOX extends BBOX {
public boolean isLoose();
}
and then sql encoders and the like could check for the interface
and the return type in order to decide how to encode the filter?

FeatureSource.getSupportedHints() -> Set<RenderingHint.Key>
