Because it is a main road and the lower speed will quite considerably disconvenience many thousands of people daily, including many buses.
Where a school exists in these spots, barriers, crossings and ideally a guardian solves the problem. The school near me (king davids) functions just fine. I would argue that if a road is very dense in traffic, that even if it was going at 20mph it would be highly hazardous to primary age kids trying to cross it themselves. The things like crossings, parents and lollipop-people make it work, and they would be equally necessary if the speed was lower.
