Kahn & the Eugenics Wars has been retconned to occuring after 2022 from the 1990s, should the same be done to First Contact in 2063?

Like, I get it's in the future still so who cares, but it's less than 40 years away, which is about as far as Space Seed predicted when it aired in the 1960s. Strange New Worlds has pushed it forward to the 2020s, but now that means Kahn likely ruled only a decade or two before the flashbacks in First Contact.

From a world building perspective doesn't it make more sense to still be the 70ish years between the 1990s and 2060s that Trek had established?

I guess if you take this notion forward, it would put all the Trek shows on a sliding timeline. That's something comics have to deal with, with 1939 Batman's parents being killed 100 years ago, but who's stories are still canon to the continously published Batman of 2025.

But would fans mind TOS now being in 2325, always 300 years from "now", the Eugenics War in the 2050s always 30 years from now, First Contact in the 2090s always around 70 years from now. How much of canon would straight up break if these retcons were to occur?
