Fromsoft probably wanted the players to look for their own answers / imagine what happened in the end. It could be implied that the protagonist in NX died in the end; he/she faced the whole suicidal battalion in an open area, unlike in LR where you would later on get your sorry ass saved by gaining access to a safe spot, thanks to either another raven or your operator.
The ability to import saved data was most likely just another featured stuff for the sake of gameplay continuity, not the story. Either that or From wanted us to have our own version. They never left us with clear answers to begin with anyway.
