Meh, and they added embed. So those who've always used embed, will blindly continue using embed except now it's legal (if they cared, they wouldn't have used it in the first place), while the rest of us who never used embed will continue not to do so. I assume the same for abbr (who still isn't in any vendor's plan to get some keyboard love). Plus, it doesn't seem anyone is paying much attention to old tags under the "HTML5" banner anyways. Only the shiny new ones. And then they don't know how to use them most of the time.
