This autoflight specific, is covered in the operational manuals and known to B777 operators and aviators, for me, the fact that many scape slides did not deploy properly or not held in place after deployment is even more concerning, as for that part, we aviators and operators are not properly warned about.
Slide limitations, not tested with winds above 25kt, or other specifics that we are not aware, this is for me a better reason for a law suit.
