True, but the sport band probably doesn't add that much to the cost of the watch. So your best bet is to do what I plan to do - get the sport band version, then ditch the band if you don't have a duplicate or are pretty sure you won't use it occasionally.
I do agree that it's annoying, though. I would have bought a sport loop package if they were offered with the stainless case. Instead, I ordered a sport loop separately (comes in later this week).
