Better tell that to all the pilots before they start landing in crosswinds! Oh wait...
Crosswind landings are no different - you'd BETTER have that airplane lined up straight on touchdown, or you'll have trouble.
Sure, the approach is flown crabbed into the wind, but you'd better have transitioned into a slip before touchdown, or, as the airliners do, kick out of crab just before the mains touch (slipping would likely drag an engine nacelle or wingtip on the ground).
I suppose I should have said "landing gear is built to handle very light side loads only" instead. The pilot's operating manual for every certified airplane in existence will tell you what the maximum allowed crosswind component is for that particular plane.
