XQuartz is X11.app. Percentage-wise, not many users needed X11 and the ones who do should be smart enough to follow the instructions they give to get XQuartz.
Apple effectively removed engineering redundancy. It allows for a more aggressive release cycle. Apple engineers still oversee XQuartz. Many of the main committers are Apple employees working on Apple's time, for example, Jeremy Huddleston.
I liken it more to the Java distribution transition as opposed to something like Messages.app obsoleting Mail.app.
