Has the Working Group studied HTTP content negotiation before making this  
claim? Say I got a file index.css and a file index.htm and Apache  
MultiViews is enabled. If the user agent does a request _all_ the time to  
/index with

   Accept: text/html, text/css

index.htm will _always_ be returned. Even for <link href="/index"  
rel="stylesheet">. That seems wrong.

Fair enough.
