This is the same in Windows 7, XP etc for the HD4xxx and older. It's not specific to Windows 8.
Put another way: previously, manufacturers used to drop older cards from their driver releases full stop. AMD are making a change and are continuing to support older cards, but only for bug fixes. Performance optimisation will concentrate on newer cards (the older cards should be more or less optimised by now anyway).
