Your are right, of course, when you concentrate on 'really' realistic scenes
and renderings.
But the old usage of variable ior could make some very nice scenes. Why
don't (re-)implement [I'm sure the old code isn't completely erased out of
the world ;-)] the old version of ior and naming it e.g.
'irreal-ior'? So you would have all we want:
1) a real ior (which of course belongs to interior becaus it's a matter of
the stuff and not the surface)
2) a nice feature for making some artistic scenes look better (even you
never can build such a scene with realist material - but why not making
irreal pictures?)
