Why can't scope be promoted and headers be _gracefully_ degraded? Why not give AT a chance to catch up? Also it looks like id/headers would fall under "Universal Access" principle which says: "Design features for universal access. This does not mean that features should be omitted entirely if not all users can fully make use of them, but alternate mechanisms should be provided when possible."
