Now that Star Trek: Strange New Worlds has brought back "proper" Klingons, it reduces the chances of a return for Star Trek: Discovery's unique version of the classic aliens. Discovery's Klingons were controversial when they first appeared in 2017, and have never appeared elsewhere in the Star Trek franchise. For many, the radical redesign of the Klingons was change for the sake of change and didn't enhance the iconic aliens in any way. It even appears that Star Trek: Discovery has disowned their own Klingons since transporting to the 32nd century.
