And that's unacceptable why? As I said before, this is obviously  
hypothetical anyway.  IE might only ship with HTML5 once MSFT could  
safely use the version string.  And if they ship with their own form  
of opt-in and don't honor your HTML5 doctype, so what?  Older  
browsers wouldn't honor it either, so you'd obviously have to be  
prepared to provide a useful rendering anyway.

Possibly, yes.  Realistically we're only talking about IE though.
