I don't understand this "without quantification". Do you think you need this because you know that you read Spanish better than English, and so on, but you don't know how much better? Or do you think it is needed to avoid click-tracing? What would you expect the server to do when receiving a "preference list without quantification"?

The second mode (get the default doc when not sending any Accept-Language data) already exists. The first mode also exists; it sends the overall best document considering your language preferences and the quality of the documents. I don't know what you mean by "best doc only from friendly servers", or why that would be needed. Regards, Martin.
