Is treyarch going to put staminup in every zombies map?

As of my last knowledge update in October 2023, there hasn't been an official statement from Treyarch confirming that Stamin-Up will be included in every Zombies map. The inclusion of perks like Stamin-Up often varies depending on the map design and gameplay mechanics intended by the developers. Players can expect some consistency in perks across maps, but specifics can change with each new release. For the most current updates, it's best to follow Treyarch's announcements or community discussions.
