Maximizing compatibility with PyGTK is a goal, or minimizing the porting
effort where possible, so if this is missing please file bugs against
PyGObject (component: introspection)

I have also CC'd python-hackers mailing list as this is where discussion
relating to pygobject and gobject-introspection is preferred.
