That train left more than 10 years ago, and nobody noticed. The applications you were using during these years used a local mechanism (MIT-SHM, DRI, etc) to transfer buffers between the application and X server. If you try to force them to use a socket (you know, to emulate a really fast network), you would not be satisfied with the user experience. So basically, nobody noticed, because nobody is using it in this scenario. That occasional remote dbca session doesn't count ;)
