I don't have an unlikable attitude or a 'case' (as far as I know).
Sorry if I caused offence. Seemed a reasonable question as to design implications to me: if everything is as it always was and their have been no design challenges (eg need for special materials to allow the design not to be limited, then fine, please feel free to say so). I am not involved in the industry other than as a paying customer, nor am I Boeing v AB, if that's your suspicion.
