Yeah, that's my take too. It's actually $$$ extra to put one on, never mind any requirement. Think your dealer messed up somehow.
If you remove it, do it early. The paint ages differently underneath it and it'll eventually make its presence obvious. I rather like mine, though--no hood glare whatsoever between the hump and the decal. I actually can't even see the hood while driving, really, which is kind of cool with the huge windshield there. Nice change from my mirror-finished black truck.
