AFAIR this has already been discussed - search a bit through old news. 
While this would certainly been possible, it is probably is difficult to 
add this to the current pov code (AFAIK somebody already tried it). E.g. 
consider that meshs have their own internal boundingbox hirarchy. If you 
still would have a boundingbox for each primitive the memory saving would 
not be big.

So we can hope for POV 4.0
