I actually feel like it is sort of important to make it clear that Leia didn’t finish her Jedi training. Luke has to be the last Jedi, after all. I actually find it funny that the writers even specified that it was her last night of training.
I agree, but I think the “surrendered her saber” and “finish her journey” lines make it clear enough that Leia didn’t become a fully fledged Jedi. Though I do love the change, if one was to nitpick, “she had sensed the end of her Jedi path” carries an implication that the end has arrived now in a way “she had sensed the death of her son at the end of her Jedi path” doesn’t, so those other two lines are doing a lot of clarification work either way. Anyway I’m just spitballing - trimming out the mention of Ben’s death already massively improves that dialogue, and V5 sounds pretty good to me. I could probably convince myself it’s a good idea to remove basically any line in this movie lol.
