Since your site is actually going through Google's cache, they could add any additional tracking, etc they like, I'm sure they're already doing this. If you don't run Adsense or Google Analytics or anything else Google JS already on your site this gives them a new opportunity to further track users behaviour with a seemingly "friendly" mobile method. It's all about tracking users and selling more ads while keeping eyeballs on Google. You're giving up control of your own site and brand, at a great expense, for their benefit. No thanks.
