Unique upgrades

Since AoE4 is fixed on Civs being more different in gameplay from one another, why don’t they have more different upgrades? In the University for example, the one building meant to have upgrades in them, should have unique upgrades. It feels so generic and boring to have those set of upgrades for every civ.

It is definitely boring, but it adds some simplicity to it all, which can be good for a lot of newer players, as they won’t have much to learn.
