Whenever a crab is maintained a crosswind approach, offset the flight deck on the upwind side of the centerline so the main gear touches down in the center of the runway.”

The upwind wing down technique will provide the least amount of torsion type stress to the landing gear as a whole.

While it may not be a specific manufacturers limitation, reducing thrust on the downwind side of the jet may have limiting performance due to go around performance and potential VMC situations from a balked landing at extremely low speeds when flaps are extended beyond the engine inoperative landing position.

Boeing has this to say about touchdown in a crab.

“…the greater amount of crab at touchdown, the larger the lateral deviation from the point of touchdown. For this reason, touchdown in a crab on condition is not recommended when landing on a dry runway in strong crosswinds.”

Asymmetric thrust is most commonly used in fairly lightly wingloaded aircraft as a technique to get a little more crosswind capability from an aircraft that has run out of rudder and can't land in a crab. It just adds a little directional control when there isn't enough rudder.
Some heavy jets can land in a crabbed or partially crabbed condition and this may even be preferable in a low friction situation. It also serves to increase the crosswind capability.
I have never seen a jet flight manual recommend asymetric thrust as a landing practice, or a takeoff practice. Would it work? Sure, but they don't want you doing it. Just like they don't want you exceeding crosswind limits or landing on an icy runway with no effective braking. Most of us don't want that recorded on the data recorder or having to explain why we were experimenting with an unauthorized method.

Most anyone can touchdown in any crosswind within reason, the tough part is what happens after touchdown, keeping control of direction after touchdown in a jet is a little different than a light twin and there is less margin in runway width, reverse and braking requirements.

I preferred not to report to Atlanta for re-training.

But that's just me -- de gustibus non disputandur.

There is not, nor has there ever been a "safety issue" for passengers. My first landing, during IOE, in a B-777 at ORD was with a sustained crosswind component of 31 knots. Does that make me Superman ? No way ! I'm just flying the aircraft "by the book". It's done all the time. For the record, the B-777 was certified for a maximum demonstrated crosswind of 38 knots simply because the FAA could not find a crosswind greater than that during the certification tests. The B-757 and 767 are similiar in their ability to handle crosswinds, as are a number of other jet aircraft.

Back to the original posting. A transport category turbojet aircraft or any jet aircraft is never landed with one powerplant at a reduced power setting (barring non-normal procedures)to handle a crosswind. One controls roll and yaw issues with aileron and rudder.

I'm sorry Professor...what am I missing ?????
