I am saying that IE8 and 8.1 in my scenario above would treat content  
with the HTML5 doctype but no custom opt-in as HTML4.01 yes.

To work with IE is going to require the opt-in, yes.  However since  
IE would presumably never drop support for any of these opt-in  
switches, the document would only need to include the opt-in for the  
oldest version of IE that they wish to support.

This is all hypothetical.  I don't think we should dictate to MSFT  
how they should opt in other than to say that if we *do* have a  
version identified via a doctype or attribute that IE should not use  
that as an opt-in until they are prepared to fully support that version.
