I think it 100% counts. Whether or not it was intentional, it's an obvious similarity.
My argument isn't that that was intentional, but it's there. Also, I'm decently certain that this one is far too perfect for it to be just coincidence.
No, no, no... Not a simple Star Destroyer, but a grand, "super" Star Destroyer. You have the Executor in RotJ and the Supremacy (call the movie whatever, I feel like that's a far better name for a ship).
Which, if you look at Rian Johnson's "obsession with subversion," is kind of a neat thing to do. He killed Snoke, made a lot of people (including myself) disappointed, but now we have no idea how this next movie is going to end. They already used their RotJ ending, what are they going to do, use RotS'? We just have no idea what can happen here, because they have no more Star Wars movies to pay homage to. That's a scary feeling, and some are upset about it, but it's kind of enthralling at the same time.
