Perhaps not.  I remember one day rendering a glass scene with and without
photons (no radiosity) and was astounded to realize that glass without
refraction and caustic would feature very little shadow after all.  It makes
sense:  caustics are the result of bent rays of light passing through the glass
and gathering at a single point or region, so the other parts of the occluded
"shadow" should really show much darker, since the light is not directly going
through the transparent material as in the no refraction/caustics image...
