Would you want an APS-C camera with an RF mount?

Are you serious? How on earth does the M mount allow for a smaller lens than RF? It isn’t a case like EF-s where a mirror was going to hit the back of the lens. There is no reason Canon couldn’t make a reduced circle RF mount lens for an APS-c sensor that is the same size as an M mount lens.

In theory, yes, although such lenses would have to have ugly bell-bottoms like contraptions to let an EF-M sized barrel match the RF mount.

In practice, there are other problems, though. When you twist a lens on and off by grabbing the barrel and applying torque, a thicker lens allows you to apply less force (lever effect). Using a thin EF-M barrel on an RF lens means you’d have to twist the lens pretty hard to dislodge it. This is probably not a deal-killer, but it would be jarring and unpleasant enough that Canon may elect to simply make APS-C RF lenses at least as thick as the mount diameter.

The bell-bottom-like contraptions could technically increase the overall diameter of the lens.

I'm not sure about this but the flange distance of the M-mount body is also shorter than that of the R bodies. Would that also not mean they are able to make smaller lenses?
