The film should want you to feel sad that Chewie is dead, not, “Lol it’s fine! Here are some jokes!” The emotional beat doesn’t land if the film undermines it in the next scene - that’s the same exact reason why the Chewie Reveal scene was cut from Ascendant in the first place.
Interesting choice of words there: “the next scene”. If you take a look at the movie, the next scene is actually a whole grieving scene that takes place on the Falcon. As a result, the film has already accomplished making you feel sad. I believe what we’re arguing about is whether or not the film should remain on that grief for an extended period of time or keep the plot going without that weighing down its options (since he is actually still alive).
