@KnS. Exactly. I would love to just be done with SS, but like you said her feelings for Sasuke have been important to the character's story line and progression. I don't even think SS shippers believe she will go back to her part one obsession, but I think it would be silly of to not anticipate something of SS nature from Sakura. Not necessarily a longing to be with him romantically, but she has to work through all the angst her Sasuke related feelings have caused her over the years. Though I dont think its absolutely necessary, I can see why some shippers need Sasuke to be reformed before they can fully accept her choice to date Naruto.
I know he supposedly doesn't think too hard about the romance, but I wouldnt be surprised if Kishi himself felt the same way.
I remember a long time ago someone said that we should fully expect SS and NH to work themselves into the story before NS get to become endgame. I agreed with the sentiment back then, and I still feel the same way today.
Hinata has said her piece. Next 
I don't want him to be with anyone, but part of me does feel like he will end up with Karin
No side shipping nonsense, I honestly felt like she was the most natural fit with him up until he sacrificed her, but I guess we are suppose to get over that too so w.e
