I'm all for more content. The main story is already set in the stone, so anything more is extra side quest and filler. Kitase said they wanted Cloud to do deliveries, and among other things that didn't make it into the game, or was scrapped completely. I will put two links below. I won't lie about this though, but my expectations is pretty high for FF7R, and I'm sure SE knows their fans expectations is high, and if it ends in failure they'll never recover from it.
to do deliveries? delivering 2 letters is hardly doing deliveries. but there is def stuff that was cut they could add, but definitely not much from the 2nd link
