IIRC, back then when Muv Luv was suppose to come out nobody knew about the Unlimited part(military one) and though it will all be just generic romcom. After Japanese went through 2 main routes and discovered Unlimited they were mind=blown. Correct me if i'm wrong about something.
But damn, age planned this VN really well. If you listen to lyrics of Muv Luv OP you can hear kinda spoilers for Alternative part
