First and foremost, I am proposing that we need to have the widget
implementation and the a11y object implementation share a bed, so to
speak. They need to have access to each others private parts. Even
more so, now that we've sealed gtk to make access from the outside
harder / more controlled.

All these are great reasons in theory, which have failed miserably in
practice, if you ask me.
