I’m curious if this will improve DLC mismatches. For example, I’ve purchased most of the map DLCs for Euro & American Truck Simulator, but my wife only purchased the base game.
By memory she previously could access all of the DLC via library sharing until she purchased it, then she could only access the base game and not the shared DLC. It’s probably cleanest to keep it that way since you never know how different games handle DLC being activated and de-activated within an existing save, but it would be nice to not punish someone for playing a game with DLC via library sharing then purchasing the game for themselves and buying DLC later
