To be fair, our collective understanding of what happens around the wheels and wheelwells (for some reason Europeans call them wheelhouses, like the Titanic) is just getting started.
For instance, it seems to be a better use of a pair of skirts to put them on the front. (shocking! shocking! It's got to look like an Ecocar!) Airflow at the rear is pretty well settled down, by comparison. (Regert)
Then there's the issue of jetting vortices at the road/tire junction. The front seems to be an area of rapidly changing pressures and velocities, and even a skirt is only a partial solution.
Then there's all the stuff like brake cooling, where the front has to do most of the work, and dissipate most of the heat.
I, for one, would cut them some slack.
