KDE is not obliged to support X11 any more than they're obliged to support JACK1 or sysvinit. They're all in maintenance mode, KDE couldn't embrace or extend them even if they wanted to.

KHTML is tragic because it had willing developers working for the public good. Jack1 and X11 are not tragic, because their developers were already drafting transition plans to depreciate their libraries.
