Why do we even have drivers/input? What in there cannot be done in
userspace? We can just remove everything but uinput, right?

Many notebooks have built-in touchpad that has only two buttons, no or
limited multitouch and is not built in a way that allows pressing both
buttons together to trigger the X11 middle button emulation.

This is a facility that exists in the kernel already and allows mapping
the missing button(s) to keys near the touchpad. Easy, works with
anything that uses the Linux input events (ie does not depend on X11).
