I never used the ambient light sensor; totally useless as far as I'm concerned. I'm not convinced "it's too thin" is the real reason for removing it anyway...probably more like "most people wouldn't miss it, so let's ditch it and save a bit of build cost". However the current iPod touch is pretty much the ideal thickess right now; I don't think I'd want it any thinner since it would start feeling cheap/uncomfortable.

But knowing Apple, the next gen touch probably will be.
