They don't, it's just an X server that works on top of Quartz, a lot like XWayland does. They used to provide it for compatibility reasons, so you can port X11 software easily. I'm not even sure it's included by default nowadays, probably has to be installed separately.

@m0xee @gabrielesvelto I see. I am not even sure about the differences between XWayland and Xorg, I am just an end user. As long as those windows work, I am happy!
