Those guys evidently think that an application without display cannot
do anything.  They forget that even if display connection is lost, and
even if this is due to some fault of the application, that application
could still shut down gracefully instead of losing all of the user's
work, if only GTK wouldn't call _exit "because it's acceptable", or
"because emacs is a 1980s teletype app", or because whatever other
ridiculous justifications these guys come up for such misconduct.

Really?  Since when does saving data to disk require a display
connection??
