Fair enough, I guess it would only matter if Gorkon was Kol's brother or something.So, Klingons may want to kill certain Starfleet personnel like Spock? How is that different from a day ending in "Y"? Other than that, I don't see how it makes much difference among Starfleet.
I'm actually more concerned now about the revelation in the interview http://trekcore.com/blog/2019/04/interview-star-trek-discovery-season-finale-michelle-paradise/ that Yeoman Colt was always meant to be an alien (and this is probably canonized in the credits?), as this completely messes up the plot of the Cage and the Talosian intentions of breeding her with Pike.
