Actually I think the main reason is simply that POV-Ray does things 
differently than all those mesh-and-shader renderers out there.

Well known maybe - but I doubt that it is a fact. The multipass approach 
has its limitations; for instance. AO breaks down for indoor scenes.

When it comes to CG movies, a multipass approach is no doubt a crucial 
timesaver, and the action hides the flaws rather easily; but for stills 
I'm sure it's not a cure-all.

This thread already spawned some background process in my brain :-) (Of 
course don't expect any such thing to appear in the very next release - 
I'm not /that/ fast :-P)

I wouldn't really consider that postprocessing.
