I can see some of the argument here - it's easier to restyle certain things when they're PNGs rather than GIFs, where animation is not a concern (e.g. standard UI stuff)
There are still quite a few GIFs hanging around (admin menu, some of the admin UI comes to mind) that probably should be replaced with PNGs - and nicer ones at that.
