Err, I've done actual before and after testing on my autox car as well as my 240.
While what you posted is mostly true, you can't speak for all speeds - the way air moves over the car at 35mph vs 100mph is very different.
I've found that cooling was better, and the intake charge was better (my itb's are at the cowl).
If its for looks, then yeah that's dumb.
