It hasn't.

> XQuartz does not replace the system X11 on Snow Leopard, so you can go back to the Apple-provided rather easily. Just launch rather than to get the older server. If you want to make Apple’s the default server (owning the launchd $DISPLAY socket), then you should disable the org.macosforge.xquartz.startx.plist as described in the first question. After logging out and back in, Apple’s will be default. If you still want to remove from your system, you can do that with these two steps:
> launchctl unload /Library/LaunchAgents/org.macosforge.xquartz.startx.plist
> sudo launchctl unload /Library/LaunchDaemons/org.macosforge.xquartz.privileged_startx.plist
> sudo rm -rf /opt/X11* /Library/Launch*/org.macosforge.xquartz.* /Applications/Utilities/ /etc/*paths.d/*XQuartz
> sudo pkgutil --forget org.macosforge.xquartz.pkg

Yes, that is correct.
