> Why should there be an X display number when gdm doesn't use X?

I dont know if those display numbers :0 , :1 are specifically associated with X
or not. But even without using X, when I run "echo $DISPLAY" from a terminal
within desktop it does print ":0" . Even exporting a display to :0 works as it
was working before. So it seems even XWayland follows those display number
conventions. Then why not log it ?
