He never said they should be. "I'd have to look at the past to be sure all are canon." That's what he said. It is pretty clear that, for now, he is not even sure himself if they are all canon.

Until he tells us clearly they are canon, we just can't consider them as "canon" because we want to. It is unprofessional.
