To me, SW is NOT all Luke's story, and I have NO nostalgia associated with the OOT. I greatly enjoy all aspects of it, just as much as the PT, but I see it as one saga, of which Luke's story is one half of.
I own a copy of the film novelization from 1977, when the film was first released, and emblazoned on the front cover, it says; "STAR WARS: From the Adventures of LUKE SKYWALKER". Looks to me as if it's Luke's story.
