There’s also a bit of a different optimization goal in modern archery - the goal is to put as many arrows precisely on a target. More draw weight helps up to a certain extent, but ranges are pre-set and limited and once your draw weight is high enough to comfortably propel the arrow that far, more weight will not improve things. Aiming gets harder at a higher weight. You could shoot a heavier arrow, but the benefits are somewhat limited - it punches a bigger hole which helps a bit, but you’re not trying to kill the target - so the added penetration is not interesting.

In a war setting, higher draw weights increase both distance and penetration, which are desirable.
