Trouble with the divergent continuity is that it renders the whole future history that is the Star Trek universe irrelevant to the new movies. Anything could happen in future installments, all in the name of entertainment, and the original 'canon' doesn't matter. Its like the Prime universe isn't real and none of it ever happened, and arguing about Klingon foreheads is somehow trivial, perhaps even silly, given that Star Trek is really just a big budget crowd pleasing movie. If an extensive knowledge of a fictional future isn't even relevant to a series of movies, then that knowledge will never be important in the real world world
