Privacy controls are indeed very important. I don't want my hardcode Halo friends to see I also play Farmville and "my talking tom".
Until Microsoft adds them, I have this to offer as relief: Nobody cares about us. They are not going to look at your bible app to discover you also have it installed, don't worry. Or are you hiding from your fellow believers?
Similarly my Halo friends hopefully won't look at the Farmville store page and discover my shame.
