TBF, white females have already died (Tasha Yar, and Jadzia Dax-even though it was a Trill). And who of the Disco cast who would you kill off? Nilsson, who's actress already played a character that got killed off in Ariam? Detmer, who’s finally coming into her own and is having the development that the audience is looking for with the supporting cast? Tilly, who the showrunners probably want in command of the USS Enterprise AA, or whatever letter the Federation are at now in the 32nd century? Reno, who would probably take Stamets job of chief engineer if he ever left the show, a position that is usually dominated by men in the franchise? Adira, who is new and doesn’t identify as a she? I have seen someone suggest that Tilly and Stamets were holding the show back and needed to go for the show to reach new heights (on reddit, iirc), but those characters can just be transferred to another ship. But its not just Burnham, although she gets the brunt of it. It's would be preferable if either the ship gets destroyed and kills the entire crew. Or the entire crew gets blown out the shuttlebay while watching a movie because of Zora.
