Nintendo doesn't include it in all their controllers either. Kind of a pain when you have to walk over to the console to turn it on if you're going to use the snes controller. Also frustrating that only some games will let you access the home menu with those, even if they otherwise work fine. (Especially the Nintendo provided emulators! Game boy works fine with a snes controller, but if you want to switch to something else, it's a hassle) F-Zero 99 supports it well though!
