In the other end of the problem: It seems that my and (I dear say) 
Maciej's bug "Permit closing tag for new, void elements - for legacy 
compatibility = XHTML alignment" is related to this.

Indeed. I have said similar things. A "warning" doesn't seem right. 
Eventually, "information" instead of "warning" could be of help.

This is the same question as bug 7056 about flow element inside 
<caption>: why are they permitted there? And if permitted there, why 
not also inside <h1>/<h6> elements?

Here I assume that Validator.nu takes a "I am an authoring helping 
tool" approach. Categorizing it as "superfluous attribute" would be 
better.

Indeed. Have already said similar things. And I don't understand why 
X-UA-compatible is more controversial than conditional comments. 
(Conditional comments typically causes authors to write document in a 
"un-semantic" way.)
