Shawn,
    Maybe I'm misreading you but are you suggesting that GTK+ should
export proxy interfaces
to be signalled by an internal GtkApplication in the code ? (i.e.
applications would set the core's
application delagate object ?).

Personally I would much rather avoid that api and have the osx
implementation of GtkApplication
assign a delegate internally if it needs to; and in this way export
IMO a saner api than Cocoa does.

Cocoa may have a specific reason why they had to add a delegate object
separate to the app
object (maybe something tied to springboard...)

Or maybe it is their preference to export such an api, i.e. see
UIViewController vs. NSView
(there is also no reason here I can see why one would rather implement
a controller proxy
than to implement the parent view, although I suspect this restriction
is mearly imposed by
the way they chose to implement nib files with Interface Builder).

Best Regards,
       -Tristan
