I think most Radiance users know how to use such an option with  
caution.  If anything, it's a nice starting point, a way to see what  
you're dealing with in a given scene.  I don't see how it's much  
different from defaulting to '-s 1000'; certainly there is potential  
there for gross misrepresentation of the luminous environment as well?
