Very true. Hinata gets a lot of focus in filler, but we did get plenty of NS filler, such as Sakura getting really jealous when Naruto was kissing that filler villain! 
Exactly !
You know what, I refuse to blame SP for this ending. I was skimming along the Shippuden episode list and I was reminded of one very important thing-- SP have given many many moments for NS in almost every filler arc.
Its true that they over-exaggerate Hinata but they rarely did episodes dedicated to NH. And SS... its pretty clear SP weren't the biggest fans of that garbage pairing. In the last couple of years they have underplayed NH moments( 631) , ignored SS completely while at the same time emphasized NS more and more.
The very recent Mecha-Naruto filler comes to mind. That 'Sakura-flower' scene was done so romantic 
The movie has been production from two years before and its safe to say SP knew all along which pairings would become canon. Despite this they did not give anything for NH/SS, instead they chose to highlight more and more of Naruto and Sakura's wonderful bond. What does that tell you? It tells me they like NS more than NH/SS.
While I was looking at the episode list, memories of all those NS fillers came to me.
Remember the Sora arc where Naruto and Sakura protect each other without worrying about their own lives?
Remember the food pills, the notes that Sakura wrote for Naruto and Naruto holding those notes close to his heart ?
Remember Sakura and Sai's conversation about Naruto during the RasenShuriken training?
Remember Sai's words-'' Sakura, you are always worried about Naruto arent you? '' in the four-tails arc? Hinata was in that arc and her understanding of Naruto was used as a comedy while Sakura was shown to really understand and care about Naruto.
Remember all those fillers after Pein arc with Naruto and Sakura walking around the village and Sakura giving that special smile of hers for Naruto when he ran off to help rebuild Ichiraku's ?
I could go on and on and on because SP gave us so many sweet moments. I can't not acknowledge this.
Remember Sakura's 'I couldn't kill the guy I used to love'? And even more importantly, remember Naruto Shippuden episode 235? That single most beautiful episode which captured the very essence of Naruto's selfless love for Sakura?
Studio Pierott understood and acknowledged Naruto's feelings better than Masashi Kishimoto himself. They understood what was better for Sakura. They have never, till now , undermined the NS bond unlike a certain mangaka. And because of this, I find myself respecting SP more than I respect Kishimoto.
