The idea is that the parallax of two objects that are say 200 meters and 250 meters in the distance is negligible and can be ignored as long as you get the parallax correct for nearby objects.

You might have to set your nearfield scale based on the contents of the scene. It wouldn't work if there were say, some buildings at 200 meters and then mountains a kilometer away. But if you're in a cathedral with some chandeliers high up on the ceiling, cheating to remove the parallax of the chandeliers will not detract from the VR effect.
