I wondered the same thing. Most metros perform load weighing to adjust the effort. Why can’t the same tech be applied to planes? It may not capture all the data needed, but it wouldn’t be off by 20 thousand pounds and it could be incorporated into a feedback loop, to increase effort if the plane isn’t getting the expected lift.
