There are deleted scenes from the Prequels that improve the storyline (like the Birth of the Rebellion, or Padme’s Visit to her Parents’ House). And I have edits that reinsert them. Also, there are films, like Superman: The Richard Donner Cut, that are developed directly from the standpoint of reintroducing deleted scenes.
So discussing scenes that made it to film but weren’t included, as evidence of where the film creator was going with it, is valid.
