Well yes, but that won't be portals or BSP. For that you'd want octree, or something like that. Ok, I suppose an engine could theoretically implement three or four different methods of visibility/occlusion but even then they run the risk of implementing in such a way that some people end up having to roll their own. I just think it's something that a game programmer should be doing, because it's often going to be game-specific.
