From what I remember from the back story of the Goobbue mounts, they aren't actually domesticated so much as we learned how to make a wild Goobbue do what we want. I assume that is one of the reasons we don't get to name our Goobbue mount because, in theory, it could be a different wild Goobbue each time we summon and dismiss it.

But from a non-lore standpoint, some kind of adjustment to either the camera while riding or the size of the Goobbue could be nice.
