This exactly summarises why we can't do this.

I don't really see how this would be particularly beneficial. Saving two
characters to specify an ID (and 5 for a class) at the cost of losing
compatibility with all legacy UAs, seems pointless.

Yes... that's why we're not inventing anything unless we absolutely have
to. Like <canvas>, or <datagrid>, or the various other new features in
HTML5. (There aren't that many. They're all pretty vital.)

HTML5 is HTML4, just better defined (fixing bugs in HTML4) and with a few
new features to handle things HTML4 couldn't do.
Please let me know if there is something that was said in this thread that
deserves further reply; I don't think there was (mostly this thread was
people disagreeing with Andrew or off-topic discussion).
