"Additionally, the pilot will avoid setting stick into the wind as it increases the weathercock effect. Indeed, it creates a differential down force on the wheels into the wind side and differential drag due to spoiler retraction.

I'm sorry guys, this still makes no sense.
I repeat - what "weathercock effect" with tricycle gear?
The only weathercock effect you might get is if the aircraft is already crabbing on a slippery surface - with reverse thrust therefore giving a component across the runway. This is the situation where it might be necessary to cancel reverse.

The danger of not having into-wind aileron is that, for example, it has been shown to delay automatic lift dump on aircraft like the 757. On one swept wing aircraft I remember it was shown that the upwind wing was still giving significant lift at 80 knots - thereby disabling the anti-skid.
Opposite aileron is essential with KOD to avoid any risk of touching wingtip or pod on the downwind side. The controlled slip merely advances that a 100' or so up the glideslope

Could an airbus pilot comment on whether the real reason for their philosophy is a risk of overcontrolling with the sidestick?
