The big rudder on the 737 makes it capable of crosswind landings way above the demonstrated limits.
I don’t look at the localizer when I fly close to the ground, but I keep the nose upwind of the centreline.
I don’t fly in a wing down/de crabbed state ever, just kick the nose straight and drop the wing just before touch down.
It works but takes a bit of coordination to get it right.
With this procedure I have done crosswind landings with 50kts crosswind in the simulator.
