She's only part of a parallel. A parallel won't solidify NS. Naruto confession to Sakura will however, since it's actual progression in their development.
For the next chapter would you rather have another pointless parallel that we have already gotten? Or would you rather have NS becoming canon? Substance vs parallel.
I mean as how Kushina said to Naruto to be with a girl like his mom which is Sakura in understanding how one of the many ways NS will be canon. Not Naruto and Sakura depending wholly on a parallel.
Maybe I should've made myself more clear XD
