The FDA's position on tobacco products is such that they realize they will continue to exist, but they certainly don't want to incentivize their continued use and development. Of course, the high cost of the application results in regulatory capture, so this is more of a handout to the existing tobacco industry more than anything. Imperial Brands and Reynolds American both own products that are grandfathered in (Blu and Vuse respectively), and can afford the cost of the applications (especially when you consider they sell cartridges fro these products at $5 a piece for under 1ml of liquid, which is why the majority of "vapers" buy higher grade equipment and liquid in bottles - these devices are less cost effective than traditional cigarettes).
