Much of what you suggest depends more on the type of "system" (stabilizer vs leveling) that you're talking about than on the weight on the jacks. Some "stabilizer jacks" are barely capable of supporting a portion of the trailer's weight while some "leveling jacks" are strong enough to support 10 times the total trailer weight and are attached to the trailer frame in such a way that they are as strong/stronger than the axle suspension system. So, depending on the system, how it's installed and what it's designed to support, limitations should be clearly identified to the owner/operator.
Not all tow vehicles are "equal" and certainly not all leveling systems are "equal".... Many wouldn't even "break a sweat" lifting 3 or 4 times the total trailer weight. When you consider there's 4 or 6 under the trailer, damage is extremely unlikely if the system is used per instructions from the manufacturer.
