If we’re using the, “No official said so.” Argument then first of all they hinted at it when marvel cut all contracts with Netflix and canceled all the shows and second of all “No official said” that they were canon either
"Intertwine" meaning that they are part of the same story. The old shows can take place in the same universe, while telling parallel stories. I personally like the idea that not everything has to lead to the same point. It makes the world feel more alive.
