Is it that they have to demonstrate during flight testing that the airplane can withstand severe side-loading on the gear?

I know they do other unusual stuff like Vmu, that they have to attach a skid on the tail to do.

Anybody at Boeing or other manufacturers know the answer?
 
That video shows how you get your demonstrated max crosswind limitation for each airplane..

They lessen the crab, but if they got out of it fully, they'd lose runway alignment in wind that strong.

It's more about not scraping an engine, with a wing low, they would trade paint with the runway...

Sweet video!

Why aren't these guys getting rid of the crab before touchdown?

The airplane can land using crab only (zero sideslip) up to the landing crosswind guideline speeds. On very slippery runways, landing the airplane using crab only reduces drift toward the downwind side of touchdown, permits rapid operation of the spoilers and autobrakes because all main gears touchdown simultaneously, and may reduce pilot workload since the aircraft does not have to be decrabbed before touchdown. However, proper rudder and upwind aileron must be applied after touchdown to ensure directional control is maintained.
