The autoland crosswind limit is 15kts with ny operator. There is no rudder channel and it will be fully crabbed at touchdown. No mention of runway state.
Certainly in B757/767 the sideslip from very short finals was more comfortable.
The preferred teaching technique to new pilots on jets was, in the flare, to reduce the crab to zero with rudder, keep wings level with aileron, close the thrust levers, OH and don't forget to flare as well. 4 dimensional flying close to the ground. Good game for the old boys never mind the new ones. Closest thing to being a helicopter stick stirer you'll get.
