I think many of us are hoping for just that. That in some way we can get closure for all of our efforts. To know it was a bug gives us a bit of hope to then revisit all of our ideas and then to see which one then triggers the event we're craving to find- if anything.
If we're to learn it's not bugged out then I think that'll completely cripple all hope we have left in finding the base color as we practically nitpicked at every corner of the Broken Isles and formed countless theories to just find it but with no luck. In the end would this have been what the devs wanted it to be? Content is great, but if there's no one to enjoy it then maybe the bar is set too high? Mysterious and secretive content is always amazing to uncover, however there must be a trail to follow to lure in wandering eyes.
