The idea of the altered timeline is to essentially wipe clean previous continuity. To wit: it never happened. Well, fine, in fairness as a reboot it can do that. And it doesn't matter who likes to assert and/or believe old Spock is TOS Spock because as far as I'm concerned ST09 didn't happen as far as TOS is concerned.
And when ST09 is a largely forgotten project from many summers past TOS will still be there as the one that still matters.
