Square doesnt 'need' to do anything, im sure it will be perfectly fine without it. Can the Switch carts contain all those games? As for Xbox, they dont really care. At this point they know its not going to do gangbusters on that system, but the difference is that its an easy port for them to do, so its a little extra for them anyway. Wouldnt be surprised if MS footed the bill to pay for the port anyway. To port to Switch will require a little more work.
