I would imagine that because some of us have issues with the regen that this is indeed a system that is working as opposed to 'cheating' the system. Perhaps it doesn't meet the requirements? I don't know but if it doesn't, FCA can't be faulted for ducking the system because the system is in use. Also I think that overall the truck industry will always recognize the use of diesels. Where it's tuff is with the diesel car market here in the United States. If VW can't make this work, and other manufacturers are found to fail as well, and they don't think they are going to meet the next requirement which is even more strict, then I can see manufacturers saying forget about diesel cars, lets keep moving forward with gas/electric hybrids, and/or total electrics... Which unfortunately would drive the cost of diesel higher because less people would be using it.
