My reasons to do something else are pretty weak but strong enough for me. One, it's ugly. Two I hate chunky proprietary seatposts. 3, yes DA R9200 is cool and amazing at this price, but I dont think Im alone in saying Id rather go with a lower/older groupset to be able to do a custom build for the same money. If they let you pick your handlebar dimensions and crank length then yea it might be the move.
