The metagameplay -- rogue reset you, permanently, when you died. Similarly when you die in FTL you have to start all over.
It's both an incorrect term (because, as you mentioned, the overlap with rogue is limited) and absolutely the correct term (because people generally understand what it means, even if they've never heard of rogue).
I think it's important to remember that language evolves, it's more important to be understood than to be correct. Shouting into a hurricane isn't going to stop the storm, no matter how right you are.
If only we were remotely close to giving everyone equal opportunities. Sadly, we've got a lot of work to do before we're there, and to some it's going to feel very unfair when they start to lose their advantages.
I'm sure there's an abstraction over all of it. The game just has to support N controllers. The number of inputs necessary to drive mariokart are pretty small (turning, acceleration, menus, items). Other than maybe displaying some specific images for each controller type, I doubt the game actually cares deeply about the full vs half controller.
