Well, problem is that happened in the Afterlife and Immortal Realm. The rules there can be expected to be different from the norm. So lacking something like Oogway saying "He is gone forever", anything we might posit will be personal speculation and original research.

The article can still say "it is unclear if Kai's ultimate defeat in the Immortal Realm means he is destroyed forever or not," but as far as tags go, IMO "deceased" covers what we canonically saw. There is no need to append it with "presumed".
