Would it make sense in an implementation to not send the Referer when DNT:1?
It is a question we (Opera) are having right now.

Usually, without DNT, we have 

GET /community/graphics/prev.gif HTTP/1.1 
User-Agent: Opera/9.80 (Macintosh; Intel Mac OS X 10.7.2; U; fr) Presto/2.10.229 Version/11.60
Host: static.myopera.com
Referer: http://my.opera.com/karlcow/blog/2011/11/24/disabling-http-referrers-for-privacy?cid=76045772


we would have automatically with DNT:1 

GET /community/graphics/prev.gif HTTP/1.1 
User-Agent: Opera/9.80 (Macintosh; Intel Mac OS X 10.7.2; U; fr) Presto/2.10.229 Version/11.60
Host: static.myopera.com
DNT:1


* Does it make sense?
* Would it be nefarious for the issue we are trying to address about data aggregation?
