well it is like this, you do not really loose the NWS it becomes restricted to +/- 1.5 degree.
On the certification page, there is nowhere written that you have to take high speed taxiways. On the landing phase that starts at 50 ft and ends at plane stopped on the runway using all decelerating devices available and only the ones which failure rate is less than whateverIcantremenber percentage.
this is why at the beginning some landing where VERY interesting in the 7X
