Why would you NOT want an additional feature, even if it seems completely useless, to you?
It still adds value to the camera and as people have already stated... there is a use for it (vertical green screen and motion graphics are ideal examples). I know people in broadcast who still shoot SD, for certain projects (the majority of channels, in UK and most of Europe are still SD).
Not everyone here is in L.A or shooting for cinema.... Hell, I don't even make films or tv. I use cameras mainly for cool elements in web/app design projects, 1K is fine for alot of things I do.
