Well, core uses CSS3 now, but it does not rely on it. For example, in  
Garland, disabled menu items are shown transparent in the admin, but  
there is still the text "(disabled)" (or similar) as well. The  
transparency is just a nice extra indicator.

Obviously we should make sure all CSS3 gracefully degrades.
