you must dont know what storm is capable of if you dont think she could instant kill everyone as well. and marvel knew the direction black panther was going (mcu) before coates started doing this thing. these things didnt become a reality upon us seeing it at the theater. I think coates is actually just focusing on tchalla which isnt a bad thing. tchalla mbaku and nakia are 2000 years in the future. at some point he will return and they will stay where they are. to think anything otherwise I think is wishful thinking.
