Yes and no. with this you can set the actual emptyItemValue to be whatever you want. For instance if you have some complex set of dto's etc, you can set the emptyItemValue to be an actual object and have it be able to work more seamlessly with other parts of the logic. There are quite a few edge cases where you might want to distinguish the empty item by some value other than -1, but still represent the selectedIndex as -1 for compatibility with the framework.
