I view most deleted scenes that were actually filmed as part of the show that they just cut for time. It would be different if they changed the scene by putting a different one in the show to replace it.
There was a scene from GOT season 2, when the show was still good, where Tyrion making Shae into Sansa's handmaiden made a lot more sense. It was easy to tell exactly where that scene would've been placed in the episode and it doesn't contradict anything we've seen. There were a few from OZ that also serve the same purpose. They only add more context to what we've already seen. It's kind of like an extended cut of the show.
A deleted scene of Nick saying he still loves Juliette and made a mistake with Adalind is a poor example. It would completely contradict everything we've seen. A good portion of the final season would have to be rewritten just to support this scene or go in a different direction once they decided to scrap it.
