This indicates that Steam Workshop support for the title will be coming some time soon in an update- either that, or someone jumped the gun big time.
Reddit user ZEEENIK noticed earlier today that Fallout 4 recently received an update, which is 0 bytes big, so a placeholder patch however, it makes one change, with the image attached to the update for the game showing the Steam Workshop logo. With the official modkit coming for Fallout 4 some time soon, it appears as though official support for the Steam workshop, which at the very least offers a way to organize and keep track of mods, for the game is also in the cards, and slated to be added to the title soon.
