Architecture contributes, but all it takes to blow input latency is some inefficient code almost anywhere in the input or rendering pipeline. The Apple IIe didn’t really have very many layers between the keyboard and the CRT. Wayland might have an optimal architecture in theory for latency — I don’t know — and latency could still be ruined by not fully optimizing the other components in the stack.
