As I understand it this is a mis-appropriation of CSS3 and HTML. What really should be used for animating graphics is the HTML5 Canvas. After all the purpose here is resource generation, and not altering the presentation of a document.
Graphics is sub-pixel anti-aliased. GIFs are not.
edit: imagine, for example, making 100 different GIFs to handle spinners all over where you want different colors, different sizes, speeds, etc etc. With this, it's just a stylesheet tweak, and they cascade so you can base it off what it's in.
IE8 doesn't support much CSS3 right now. http://msdn.microsoft.com/en-us/library/cc351024(VS.85).aspx
