The more significant DoS condition is another user taking the name you want, which can happen in the abstract namespace but not in a directory only you can write.
I don't have any of those. If the X server is running as root (like in the gdm case) then I can put the socket wherever I want. If it's Xvfb, then where do I put this directory? $HOME ? Nope, might not be there. /tmp/$USER ? Won't work if someone else mkdir'd /tmp/ajax before I did.
What about the XDG_RUNTIME_DIR (/var/run/user/$USER) from systemd?
