To me, it’s an ok joke, but nothing that breaks the movie without having it.
Im still not sure your hang up about the 3P0 “sacrafice not meaning anything” with this edit. In this edit without him first mentioning it is clue AND translate it and Rey now understands she needs to give in to hte Dark to use it … it wasn’t possible without 3PO. So I don’t get the hang up honestly.
Heck, even in the regular cut of the movie, Kylo suddenly appears and destroys the Wayfinder. So everything the crew did regarding the finding of the Wayfinder was a moot point.
