Sure, that is one way to view it from the technical side.
OTOH, I just like to know Kirk's fate, whether he died in "Generations", or lived to an old age in "Relics" or got resurrected in the novels or whatever new fate has in store for him in Abrams-verse.
Huh, that was pretty easy to use a new universe. Cool
Then again, I just treat them as different Kirks. If Roddenberry were alive, I suspect he'd monetize it as alternate universe and one-shot stories like how they do Superman. The Golden, Silver ages, All Star Superman, DCAU Superman, Live Action Superman....
