Per contention above, r-.

Why would we want to let servers know it's a prefetch request?  We don't let them know other things about how we're going to display or not-display their content.

For example, we don't tell servers that we're about to display their content in a display:none iframe.  Or on what screen size, etc.  Proxies also don't necessarily tell servers that they're a proxy and thus not displaying the content...  This seems like an invalid bug to me.

A request is a request.  If servers feel they need to filter out requests based on what was done with that request, it seems they should be gathering that information differently (like via JavaScript?).
