Ummm, total myth Jack.
The frame is plenty strong to support the vehicle on a lift for no longer amount of time than what it will be there.
The torque tube has nothing to do with supporting the frame. Furthermore, if the frame were as weak as you are trying to imply, then think of the frame warpage that would be caused if you jack-up an axle to change a flat tire, -or parked on uneven ground. The axles support the frame from both ends. Maybe that is why the frame sags. If you are supporting it 24" inward from both ends, that supported area is better for the frame, if anything.
