Care to mention sources? I'd be surprised if they did simply because it'll cost money that could be earned otherwise. Also I think you confuse bad block remapping with wear leveling and even the former I haven't experienced so far. CF disks were designed for simply the reason of having an empty disk, writing data onto it up to a certain level, reading it a few times and emptying the disk again. So except for the organizational blocks and "the end" of a disk which tends to get rarely hit there're a well distributed write utilization.
