I wonder if this storyline is the primary reason Filoni was brought onboard? It’s sort of like how Ronald D. Moore essentially became “The Klingon Guy” at Star Trek, because he was more or less the de-facto expert on their culture after reshaping it through his episodes.
Filoni is that for Mandalorians, probably. Especially since it seems almost like Mandalorians are the Star Wars version of Klingons now.
