Sure, I can fix it in my systems, and have done so. But other users
using the default settings will still have a potential security
vulnerability in their systems.

And the X11 files is a case we know about; there might be other programs
using /tmp in a similar way (such as the TigerVNC case), and some of
them may also have security implications.

Looking at the big picture, the underlying cause may very well be that
programs are using /tmp "wrong". The solution is to fix *all* of them,
or to accept that this usage happens and try to minimize the danger. At
the minimum, the *known* security issues (like the X11 files) should be
fixed one way or another.
