It seems counterintuitive to me that having produced fallback content

IE9 won't come out requiring WMV or a similar issue with a different
UA).
Are there any other elements in HTML that _require_ Javascript to
provide a good UX?
What's wrong with using JavaScript to work around temporary problems? In
the long term, is there a use case for allowing fallback content?
I'll freely admit that the most important reason I oppose this is because
I don't want to implement it, because fallback behavior is a mess (see
<object>). If there is any other browser implementor that thinks fallback
is a good idea, it might be worth discussing.
