I brought up this same concern in Dec 2009 and Hixie seemed to concur:

(see http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2010-February/025028.html)

I'd argue that while we did receive in WebM "a common codec" it does not enjoy the sort of universal adoption required to be able to mandate its support in the spec, so on that logic, I think establishing a declarative fallback mechanism is probably required to prevent a situation where you cannot write a robust HTML5 page with video and without resorting to JS.
