As surprise to the Mozilla community? What about the just mentioned 
"matching implementations" motto? [1]

In zero change proposal (Mark IV) you claim: [2]

]]
POSITIVE EFFECTS
* Encourages authoring behaviour compatible with both legacy user 
agents 
and with conforming user agents.
[[

But here is an example to prove that it is not true:

        div[lang=""]:lang(en){background:red}

The above CSS selector should have been "impossible". However, 
regardless of whether we went for your proposal to remove META 
content-language altogether [3] or  for zero change (mark IV) - the 
current text,  this "impossible" selector would "work", in Mozilla. In 
both XHTML and in HTML. All it takes is to serve the page with a 
content-language HTTP header (with a single or with multiple language 
tags - that's not the issue):

http://malform.no/testing/html5/attr-lang/mozilla-lang-lottery/

The issue can be cured, through a HTML4 and XHTML1 valid use of META 
content-language:
http://malform.no/testing/html5/attr-lang/mozilla-lang-lottery/fixed

Thus this issue is also related to authoring requirements - bug 
7034.[4]
