This makes sense. Google uses tracking URLs/JavaScript for quite a while now. I am sure they compiled a lot of information regarding what people do and don't click. I am sure it will be for our users' benefit. I'd wait and see the actual results.

P.S. I am think to prefetch AdSense URLs too for the benefit of my users. j/k
