Especially for animation the CSS-draft is pretty incompatible to SVG/SMIL due to this decomposition. And a SMIL animation is always performed on the provides values. This does not fit to the idea of the CSS-draft to decompose for example a matrix in a larger set of transformations and to animate these. To have this, one needs maybe another calcMode 'complex' to cover such a complex animation behaviour. And of course, for such a complex behaviour, the animation function should be explicitly and understandable defined to be understandable for an average author. A good approach would be of course just to leave the old attribute transform as it is and to introduce a new attribute transform2D to avoid most incompatibilities and to allow authors in the future to get access to this not only as a decorative issue with CSS. Of course this would be a big advantage of millions of existing SVG documents too, because there is no risk of backwards incompatibilities in the drafts or implementation problems for the old documents. The separation could work similary to animateMotion (and its attribute rotate) as additional transformations, one just has to define a proper order of all these independent transformations - well it is just one more with transform2D.
