This definitely is within the realm of full introspection; the C function signature doesn't tell everything we want to report in the introspectable information. But there are certainly bits of the GTK+ APIs, especially the low level parts of Pango, that may not be presentable in the introspection API. We should only go as far as reasonable and definitely keep the goal to "can we automate language bindings to GTK+ and similar libraries", not "can we automate lanugage bindings for any old C library out there".
