Me personally? I don't see a reason why it needs to drop anything. It does have defensive weaponry, so it could drop parts of it, or simply scientific data material, as there is no reason it shouldn't be able to. It's a generator, of course you can gather data about it. Doesn't matter anyway, as I don't believe it will ever drop anything or have a more specific reason from the devs without Treewyrm continuing the work on his vision.
