You are right of course - we still need to do more tests if we get a 
hit. But I'm wondering, does getting a hit allow us in any way to avoid 
testing objects "further away" than the one hit?

(I don't know how POV-Ray's bounding and space partitioning works - 
especially the new octree thing. And obviously POV-Ray supports infinite 
objects and so forth...)
