Well, from what I can work out, divine_blood = yes makes dynasties unplayable unless you own the Expansion, so if we want to use that they we'll have to make the Targaryens unplayable for people with only Vanilla. It's just paradox's way of trying to get us to make the new DLC a requirement for the mod to generate more sales.
Not necessarily a bad thing, if we make the mod require SoI then we can use the multiple wives thing for Wildlings and (potentially) Ironborn, although somehow make it so additional wives for the latter can only be lowborn.
