My guess would be because the idea was you would only need DEF when you did an oil change about every 5000 miles. I never fill DEF except when I go in for an oil change. I do it myself because I'm not going to pay what the dealer wants for DEF, but haven't needed to fill it between oil changes. I have once seen a low DEF warning while driving and towing, but also had an appointment for the next week for service, so filled just before taking in for the service.
