Torque BSP Vis-Occlusion

I've noticed that the Torque BSP System implimented in Torque does not occlude.
Now this is fine, because Unreal Tournament 2003's BSP system does not occlude either. But they have a thing called an anti-portal which is basically an occlusion brush that can be placed within bsp brushes to block visibility behind it.
I see nothing in Torque like this and I'm wondering why? Wouldn't it be to the benefit of areas containing large buildings to have such an occlusion utility?
To see what I mean, here is a picture from Ut2k3's editor:
without occlusion:

And the approach is compatible with portal engines, generally.
I'd say it just wasn't necessary to go to the trouble for the performance they were looking for in Tribes 2, which really didn't have a large amount of buildings on any particular map.
