Alan, I agree with the spirit if your post, and was thinking the same thing when I first read there were no exceptions- that even if the code DOES require receptacles to all be childproof/child resistant (what's up with this "tamperproof" stuff? There's nothing "tamper proof" about those designs!), that there should be exceptions to receptacles that are inaccessible to a child- EG, at least 60" off the ground, or located behind large appliances, such as refrigerators or washers.
This will impact the 12' rule, though, if people start using this to skirt the tamperproof claus- if the receptacles are 5' above the floorline, that could be no further than 6' apart for a 6' cord to reach one from any point along the floor.
