Honestly my head canon after TLJ was that Luke didn’t really “die” from Force projecting himself, but confronting his greatest failure (Kylo Ren) and forgiving himself caused Luke to achieve enlightenment, and he just became one with the Force as the next step of his ascension.

I had hoped Luke would’ve played a role that was different from the Force ghosts that had appeared before, but it wasn’t that different honestly. That is something I liked about Acbagel’s Sequel Trilogy edits, because he does add elements that try and depict Luke that way. But I guess it is a difficult thing to balance, giving him more influence on the story without taking away from the new characters.
