Compare that to all the sci-fi looking things like Nanite and Lumen which completely change how we approach building game environments.
Like, consider that you never actually need to scale anything in a perspective view, because you literally can't tell the difference (all the rays remain the same). In an orthographic view, scaling is the only way to actually zoom in/out. Oops, any code that assumed your view is unit-scale will break.
Perspective vs orthographic literally affects every single one of those fancy features you like.
It is still the kind of basic thing that everyone who has written their own renderer has done, compared to all their other ground breaking new tech. Which is funny to me.
