They are probably gearing up to restructure the whole continuity into something more digestible, and the first thing they would want to do in that case is decanonize Heroes and XenoVerse

If they are setting up the Anime timeline to be the "Third" universe 7, per Daima, that means they can make the manga the First U7, GT the Second U7, the movies the Fourth U7, and so on
Now they have a timeline multiverse that's much easier to understand, are able to write arcs that cross the timelines over with each other using the Demon Realm, "canonize" GT, etc etc. It writes itself.
