Dreadful. The shock to the gear...
To quote from both the Boeing 787 and B777 Flight Crew Training Manual:
The airplane(sic) can land using crab only (zero sideslip) up to the landing crosswind guideline speeds.
It goes on to mention that it is not recommended in strong crosswinds on a dry runway but purely for the reason that the aircraft lateral deviation on touchdown in this condition is large.
While it is clear that the stresses on the undercarriage when landing like this are large clearly the design caters for such stresses. It may not look elegant, it may be less comfortable but it is certainly acceptable if the manufacturer says you can do it.
I presume if the aircraft which is the subject of this thread was being operated by Airbus themselves then their airframes are also capable of landing safely with crab.
