That depends on your understanding of "White" and "Black..." you could very easily have a world where people with biological features we call "white" in this world exist but doesn't see themselves as "white" because nobody in your world invented whiteness for the purpose of colonialist exploitation and enforced it on almost the entire planet. On such a world, "black" wouldn't exist either... essentially, it's what our world was before European colonialism.
That's the thing with a lot - if not all - of these "reincarnated in a different world" type of stories - they are decidedly racialized, despite the fact that the question of race is either completely ignored or handled in a rather cringy and hamfisted manner.
Sooo... would it be weird. No... just unusual vis a vis our world where white supremacism is decidedly real. And oh yes... there will be complaints and even more reactionary whining. But, on it's own, that's never a reason not to do something - there was even some whining about Wakanda, despite the fact that Wakanda is based upon a very superficial western fantasy about Africa that has little to do with Africa or the people that actually live in it.
Because then they can patent it.
So it's no surprise that Bill "Anti-Food-Security" Gates, the world's most famous patent racketeering parasite, has his vile little fingers in this.
