::outside covers only a part of the use cases for wrapping elements - 
wrapper containing more than one child elements cannot be replaced by 
::outside - consider the very common case of a centered page:

   <div id="container">
     <div id="contents"></div>

#container { margin:0 auto; width:50em; position:relative }
#contents  { margin-left:10em }
nav        { position:absolute; top:50px; left:0; width:9em }

This case would require some kind of body::inside pseudo element, which 
I cannot find in the CSS3 Generated and Replaced Content Module spec 
right now. (Well, sorry if I get too much off-topic now.)
