The "extra piece" is forming a deeper handgrip 
in front of the body. The only piece which is going into the body, is the rectangular plug with app. two dozens of contacts (so it's really the question why they don't charge the in-camera-battery from the grip...). But why would you want to separate the grip from the body? The grip for my D810 has a nice cool place in a drawer. Since it doesn't really add a lot of value (in terms of versatility), but a lot of volume and wobble on a tripod and needs an extra, extra-expensive L-bracket for the tripod, I rather take two spare batteries than the whole grip and still save space in the bag.
With the Fuji grip things are a lot different because of a big extra versatility, higher performance of the whole system and even if it would be as "flexible" as the Nikon versions (I doubt that), the shutter vibration will be much less or none at all (electronic shutter).
