Funny, almost everything in the market says the "killer graphics server" feature is extremely high performance, flicker-free video from frame 0 and HiDPI support. X cannot do either of those things, period. It just wasn't designed for it. Extremely vocal minority users like you and the others on Hacker News are simply not in anyone's support matrix. Luckily, all of you folks crying for the lack of this feature are all tech experts - if you want it, go code it up yourself. Meanwhile, anyone and everyone else that cares will just switch to VNC and move on as if nothing happened.
