IMHO....
It seems to me that any place the code requires GFCI protection is a place where there is a likely opportunity that there is a chance to come in contact with only the hot conductor and another grounded surface as in metal water pipe, damp earth, concrete etc. If the likelyhood is not there I do not see a reason for the GFCI protection. So if this room has water proofed walls and wall covering with water proof floors and a floor drain and they intend to clean it with a hose..... Well, your the inspector! Please post back on your decision.
