That's a very good point. Apparently, Tuvok didn't love his wife and children as much as Sarek loved Burnham, or T'Pol loved Trip.The Klingon cloak is problematic. The Suliban had them but i think the reset button might have fixed that. I may be wrong but i half remember Kang or Kor on DS9 saying their ship was one of the first to have a cloak. As augment Klingons have been wiped from the Discoveryverse, will that still be canon.
Also interactive holograms that gives real time communication throughout the quadrant and Jedi Vulcans who communicate similarly through the mind im surprised USS Voyager with the holograms and the vulcan Tuvok didnt communicate with Starfleet earlier from the delta quadrant since the DIS apologists say all this is canon...
