That's what the current quality settings already do...
The original poster asked for the quality settings to be usable for other
scene elements. The fact is that, when working one a moderately complex
scene, it's just more flexible to create one's own switches and dummies to
manage this, including textures, shapes, lights, radiosity, media etc. What
one considers to be part of a rough draft is basically scene dependent. I
may very well fine tune the radiosity using a dummy object with high rad
settings, and fine tune the corresponding complex object with low rad
settings etc.
