You likely don't want to squat super wide raw for two reasons. First, as you mentioned, the gear helps support the hips. Secondly, and likely more important IMO, if you lift raw you likely have to hit a deep squat (hip below the knee). Most commonly the feds that allow multiply gear are also the ones that shoot for a squat to parallel depth.
Those last few inches make a huge difference and a stance that will work to get you to parallel will not work to get you well below parallel. Most raw squatters will squat with a form that is pretty similar to what Rip recommends in Starting Strength, with their own small personal modifications.
