are these comments intended?

They're needed to enable feed content type handling. Currently we're "handling"
these types by overwriting the type to plain text.

   if (mime_type == "application/rss+xml" ||
       mime_type == "application/atom+xml") {
     // Sad face.  The server told us that they wanted us to treat the response
     // as RSS or Atom.  Unfortunately, we don't have a built-in feed previewer
     // like other browsers.  We can't just render the content as XML because
     // web sites let third parties inject arbitrary script into their RSS
     // feeds.  That leaves us with little choice but to practically ignore the
     // response.  In the future, when we have an RSS feed previewer, we can
     // remove this logic.
     mime_type.assign("text/plain");
     response_->mime_type.assign(mime_type);
   }
