1) Continue to support Bindable, but move it out of pivot.wtkx, possibly to pivot.util or pivot.wtk. As a result of this move, we would lose support for @Load, since it depends on WTKXSerializer. However, we could retain support for @Bind.
In case it wasn't clear, the implication of this change would be that Component could then concievably extend Bindable. However, I still think #2 is a better option, for the reasons outlined in the previous message.
