Absolutely, don't get me wrong, it is negligible. Also, you're right, the roll in normal law is a roll rate, so again there's no gain with the airbus for landing with CONF 3. I was just outlining the general arguments for landing with a lower flap setting in a crosswind, albeit thinking more in terms of a conventional aircraft.
I'm not an advocate for it. Like I said, I've used it myself a few times but didn't see any discernible difference over CONF Full.
