Indeed. Especially important when you remember that most of the (many!) devices in a car sitting on CAN buses come from outside suppliers, and black-box testing of these modules can only go so far to verify the CAN implementation and stability.
AFAIK, Ford actually mandates that their suppliers use a standard CAN stack provided/licensed by Ford (FNOS, the Ford Network Operating System) to try and ensure a level of quality in implementations. It's a good idea, one I haven't heard of other automakers doing (although I'm not in the industry any more)
