The distinction here is that all of these are either removed features or correctness of document semantics, and therefore don't affect implementation behavior. An implementation that implements both HTML4 and HTML5 will handle all of them, and therefore authors can transition gradually between the two (although they'll technically not be conformant to either while doing so, and many may well stay in that state permanently). (The value of having these things as changes in HTML5 comes from authors who use conformance checkers that will tell them to avoid these bad practices, not from implementations behaving differently.) -David -- L.
