The more I read about this, the more I get the vibe that they're going to spin her off into her own movies under a different designation (006?). She's 007 at the beginning of the film, but Bond comes back and re-assumes the 007 designation.
Europeans are usually smarter about feminists issues than we are. Not so all or nothing. Plus, I don't see the owners of the franchise willing to risk killing their golden goose.
This is an attempt to nullify the calls for a black Bond. They can point to her and say, "Look, we have a black super agent in the franchise." Now, they can keep Bond and all of that alpha male, white woman magnate swagger, firmly in the hands of a the white male. This knocks Idris (and any other black actor) out of the running for the next Bond.
That's their strategy and it's working beautifully for them.
