I certainly can't speak for Microsoft, but from what Chris Wilson has 
said, I'd expect that they would agree with this need not to break even 
non-conforming pages (as do I).

How we go about this is another matter.  I'm convinced that a version 
attribute is the way to go, while others contend that the language 
itself must incorporated (almost) all the features of past implementations.

To me, the idea of a version that clearly identifies that the page will 
be treated strictly according to the HTML5.0 standard, and which will 
produce visible problems if not coded correctly, gives us leeway to be 
less inclusive of past quirks.  If the language is designed correctly 
(and I have no doubt this group could do so), then the leaner syntax 
would still degrade gracefully in older browsers.
