I'm really confused, this looks like concern trolling because there's a live demo for exactly this A/B testing, that IIRC was near the top of the article, close enough it was the first link I clicked. But you're quite persistent in that they need to address this, so it seems much more likely they silently added it after your original post, or you didn't click through, concern trolling would stay more vague
