imo, the fuss is cuz of the usefulness of it. even without specific jutsu that would make it a more powerful kkg (like the mirror thing for ice release), it still bijuu lvl (depending on user) and has some of the best hax abilities seen yet. and its rare as fuck, so there might be some mula involved.
