you can get the option group from GTK+/GDK, and even do so without
opening the GdkDisplay; these will take care of the GTK+/GDK command
line options (while they are still there).

there are least three or four different ways (and probably more that I
just don't see) of doing command line argument parsing with GOption and
GApplication; the examples in the GIO documentation and tests/ directory
are a demonstration.

there's also the matter that GOption was written way before GApplication,
and the API of GOption is constrained by its location insize GLib. I
wouldn't be surprised if at any point in time we just added some command
line option parsing API into GApplication itself.

ciao,
 Emmanuele.
