No, you’re being completey hysterical.
It's just a plot device.
My guess is that Lashana Lynch won’t even be in the film for more than five or ten minutes. She may not even be up to the job and that’s why Bond has to come out of retirement.
Bond as a character in the films really hasn’t changed all that much in the almost sixty years he’s been around. And there’s no reason to think he will change radically in Bond 25 or later films.
Phoebe Waller Bridge, one of the writers of B25 even commented on this, saying:
““There’s been a lot of talk about whether or not [the Bond franchise] is relevant now because of who he is and the way he treats women,” she said. “I think that’s bollocks. I think he’s absolutely relevant now. It has just got to grow. It has just got to evolve, and the important thing is that the film treats the women properly. He doesn’t have to. He needs to be true to this character.”
For me, Bond remains - at core - a cool, stylish loner & womanizer; tough, ruthless, gentlemanly [for the most part], reliable, resourceful, skilled at violence and getting himself out of a jam, often through improvisational thought. Even that he drinks too much.
Mostly what has changed is the world around him, and the films have usually tried to reflect this.
You can call it a “feminist agenda,” but inarguably the public place of women in the world is very different from what it was in 1962 and the films have attempted to reflect this from at least as early as the 70s, when we had the first of the near-equal “Bond girls” with Major Anya Amasova, in the TSWLM, and Dr. Holly Goodhead [despite the name, lol] in Moonraker.
By 1995, when Barbara Broccoli [a woman!] began to exert her influence over the franchise, the character of M, Bond’s boss, became herself a woman, who famously charged Bond with being a “misogynist dinosaur.” That was 25 years ago! And I’d say the Judi Dench character was one of the best things to happen to the series in all that time, bringing a new, very-contemporary level of tension to her relationship with Bond.
Another change that has worked for the benefit of the series is that, more recently, other secondary characters, Felix Leiter and Moneypenny, have been played by black actors, in my opinion, both much superior in their talent to the white actors who had previously played those roles.
B25 is almost certainly Craig’s last film before the franchise returns with a new actor as Bond. You can be reasonably certain of two things: that the new actor will be male, and that if he does not begin the film as “007” he will almost certainly end it having again that designation.
