Thanks for the quote, OG. Yes, one mainwheel has to suffice. Landing with residual bank (e.g., deliberately on the upwind main gear in a strong crosswind) provides routine ground-spoiler deployment, encouraging the downwind wheels to touch down in short order, even if the pilot leaves a lot of into-wind aileron applied (in the transition to ground law). The sudden loss of roll-spoiler effect is partly responsible, of course. With the nosewheels down, IIRC, nosewheel steering is not available above the 72 kt ground-speed, whether rudder-fine or tiller.
(Excuse the off-topic memoir.)
