> Is it possible that Apple’s implementation uses less power and hence conserve battery life? On WebKit, you can still use WebRequest to intercept and log all traffic, you just can't block it. I don't think that intercepting/recording all traffic and selectively blocking it would have a meaningful difference compared to just intercepting it all and letting it through.
