The problem is that sRGB is not a profile, but a colorspace. So soft proofing on sGRB is in some sense, senseless. It needs to be, for example, sRGB on a monitor, or sRGB for XYZ printer etc. Yes the next logical reason is if it doesn't make much sense, why can it be selected? The answers are a) there are probably times when bitty heads want that done for some purpose, and b) because.
