In my list above, I view GT as on the same level of canon as movies. Though possibly, along with the first cooler movie, a little bit more since Toriyuma had some, albiet minimum, involvement. Meaning that, if it breaks no canon, then it's fine. If it breaks signifigant canon, then it's not. So, that's why GT is not canon here.
