This was only relevant in the past when 3D APIs implemented fixed function vertex processing. Today this is just a contract between your CPU-side code and your shader code.
There are other other subtle coordinate system differences though, like the framebuffer and/or texture origin being in the top-left vs bottom-left, or clip space z ranging from -1.0 to +1.0 or 0.0 to +1.0.
