I guess we should mention GtkApplication here then:
http://library.gnome.org/devel/gtk3/stable/gtk3-General.html#gtk-init

Do you mean, during g_application_run(), or earlier?

But don't (bearded) people expect applications to take (GNU?) standard
command line options, such as --display=DISPLAY?

If we really think people should do this:
  gtk_init(NULL, NULL),
or
  g_application_run(NULL, NULL),
then surely we should say so in the documentation. I don't like the
vagueness right now.

The documentation currently doesn't even say that NULLs are valid
values:
http://library.gnome.org/devel/gtk3/stable/gtk3-General.html#gtk-init
http://library.gnome.org/devel/gio/unstable/GApplication.html#g-application-run
