This affected the disabling of any emissions EQUIPMENT installed on a vehicle. Since the 5.9L only have in cylinder EGR which is a combination of the CAM and tuning, there is really no real emission EQUIPMENT to affect. In order for it to affect the 5.9L, they would have to do away with the ability to tune all together which I don't see happening.
