[Bug 18669] Switch from is= to <tag if a decision has been reached among implementers

https://www.w3.org/Bugs/Public/show_bug.cgi?id=18669

--- Comment #39 from Ian 'Hixie' Hickson <ian@hixie.ch> ---
FWIW, while I used to agree that fallback in the markup of the form:

   <newfeature> foo <oldfeature> bar </newfeature>

...was the way to go, what I've seen of authors using new features in HTML
suggests that in practice that's not how authors do down-level shims. For what
I've seen, they tend to just use JS to swap in their HTML instead.
