That's one thing I loved about Orange Box on 360 & PS3 and hated about most other FPS games on consoles. Killzone 2 especially.

Is it really that hard to include from a development point of view?

DOOM3 is my all time favorite game from my all time favorite developer. Make RAGE the next best please.

RAGE will likely have control schemes, but is it really that important. Adjusting to a new control scheme doesn't take that long.

No bad thing that comes with it. Is that some are accustomed to using other buttons. Id Software Ojala consider that option and put the customization of all controls on consoles.
