I've always been morbidly curious about how such a thing would play out. Given how officially player-run holiday events are treated (being reported on in Dom Watch as well as, if I recall correctly, staff-posted wrapups), despite there being nothing similarly official granting the dom team authority (or even recognizing the existence of a 'dom team' as an entity), the fact that there's never (in my recollection) been a situation where multiple full-fledged teams were warring over whose event listing was the 'real' one seems like very lucky happenstance.
