As noted above, toward the start, consensus was already reached on this issue in the original 2016 Faction Paradox threads. No new evidence has been brought forward in this discussion. To reiterate, the current requirement for the "Homeworld" treatment is that a DWU work which is licensed for the element makes that connection. In all subsequent works licensed to use the "off-brand" name only, we continue to treat it as one DWU element, and pipe switch as necessary for the appropriate in-text treatment.
Closing this thread per T:POINT. I encourage those who wish to pursue these specific cases further to visit Talk:Auteur and Talk:Kelsey Hooper. As with every other case, they must pass muster. Refer to the above (as well as Thread:208233#14) for the applicable standards to bring up in these discussions.
