Even if Boba Fett comes back, we still won’t need Din obtaining the armour. Especially if you open on Tatooine with him in the cantina with the armour and mention his search for Mandalorians in the crawl.
This season will have more serialised plot elements, anything you can do to cut things down will help. That’s part of what makes the comedic cut from misgivings to damaged ship so efficient in something like this… cutting out nearly two episodes without having to add anything back from the other season.
