Even if some teams can find ways to minimize the additional costs in space, weight, and air doesn't mean they don't exist. By default, adding the additional gearing and shifting mechanisms will take up more space and weight than not having them. By default, triggering a pneumatic cylinder to shift will consume more air than not triggering that cylinder.
Heck, some teams might not even install a pneumatic system if it weren't for two-speed drivetrains.
