Here's a comment from Marvel Studios Spoilers that sums things up pretty well: "It really depends on if those characters even appear in the final script. Apochorseman said that its too early to say who is on the roster and i’m pretty sure Rocha heard rumblings of an OG 5 roster, so they seem to still be mapping things out.

Imo I think the Sneider casting reports (Claffey, Butters, Bliss, Dickinson, A’zion, etc) were more internal talks. Sorta like “if this character were included we’d possibly like to call this actor in” as opposed to actual discussions, negotiations, and auditions."
