There is nothing in the text of the new films that there’s a Hayden ghost or that Jedi Rocks exists. Quoting shots from the SE isn’t at all a declaration of support from the filmmakers.
The filmmaking method is also more similar to the SEs. Seeing the people on Hosnian prime as it blows up was not in the style of the original films, it was in the style of the SE Cloud City crowd shots.
