My point isn't that other applications would set or use DISPLAY. It just means that DISPLAY could be set (from someone's profile) even if X isn't running.

Just like that PERL5LIB is set if I run a Python program. Nothing but Perl is using PERL5LIB as far as I know, but that doesn't imply that if PERL5LIB is set, I'm running perl.
