Retractable front control surfaces are a very small optimization. I don't think it makes much difference. But if we assume that the 095 has them, it means they held nothing back.
I don't know guys. Retractable front control surfaces, hull sections with a diameter of 12 meters (which we saw earlier), X-form rudder patents, etc...
I think the 095 will impress a lot of people. But I am not going to make definite statements as nothing is certain.
