I would say templates are more useful than voids.

But all you have to do is remove the white from the void to get all the wheel and cockpit details as well as rivets and panel lines and such. Also, the panel lines show you what area to paint.

I guess I just figured it would be less work for a modder to add only the aircraft details instead of providing a full template ... less work for him.
