Seems an application-specific issue to me. I would accept a patch at cafe-ccic limiting the minimum resolution (as it is device-specific), but I agree with Jon that limiting it at the sensor is not a good thing to do. Getting full res means to require higher bandwidths at the bus (and this may be a problem if someone wants to have more than one camera, and the bridge is USB). Also, it will eat more CPU to downscale.
