I can’t help but feel like adding the bunk is a change for the sake of change. Like the Jedi Rocks number. There’s nothing wrong with assuming that there were a few changes made to the Falcon in the 31 years between Episodes V and VII.
I don’t really think it’s fair to compare a background bunk that most people won’t notice to something like Jedi Rocks, which replaced almost an entire scene with CGI and a new song.
