Imo, 6 years of development since Fm7, nearly 14 years when you factor in that they’ve known about more cores and more cpu threads since Xbox one.People calling this a 'disaster' just keeps pushing the hyperbolic cynical nature of PC gamers these days,
the next Xbox will have even more cores (12-16 CPU likely) but it’s never going to be able to get above 60fps if your code won’t scale above 6.
If it was never brought up as being a potential bottleneck for performance I would be surprised. The decision making is baffling here
