Understand. the risk of breaking would seem to vary by the nature of the support and DLC (eg adding new assets to existing folders vs changing existing assets and folder structures)
fwiw, FO4’s creation kit was available before the Far Harbor (and other) DLC.
Was more insinuating since there’s no line it’s a goal instead of a plan. Assumption being (per good project mgmt practice) a plan would have a date even if tentative
