Well, they did put a hard autotrim limit on the A320 - it'd be a tragic irony if they didn't do it on the widebodies in response to pilot complaints regarding lack of full authority.
So you agree now, that the NU trim should have been designed to stop like it does in the A 320. That is a big advance in this discussion.
You have evidence for your assumption concerning the cause of this change in design?
Afaik there might be lot of other reasons, why do you suggest it was caused by pilot input?
