The only scripting support I can see a need for in simple images (img and CSS) is simple DOM manipulation (deletion, creation and read-write access to objects, no events). Why not simply block anything else, and not allow the SVG to access anything outside its own document (no cookie access, I can't see an use for it either in simple images)?
For SVG applications that will take user input, ordain the use of the object element.
