Honestly, this seems like a poor choice of interlude to show to us, at least if it's actually canon.
We care about reality, and we are (evidently) a vital component of Hazou's mind functioning. We are going to care about that Kagome, one of the few character's we've bonded with over the course of the quest so far, is exposed to this side of reality, and we're probably going to end up pushing for Hazou to try and learn about this from Kagome, which in turn means that's the retcons are going to become a plot-point, which is bad because it means that you can't retcon freely, which is the whole point of retcons.
