First off, we're obviously all way ahead of events here. All we've heard is that an email's been sent to a few people announcing a private beta, so it's unlikely this test is finished before sometime in Q2. If it goes production after that (I assume not all AdWords features that were beta eventually went 'production'), then it'll probably be an opt-out feature. Opt-out's onerous enough, but I'd bet a dollar against a penny that you can, at least opt out, so there's no reason to be alarmed by this.
