The AI shouldn't be overly bothered with the survival of their dynasty, as they don't 'game over' like a player would do, their lineage is more important to them. Just to clarify, first and foremost matrilineal marriages are a player tool to avoid game over, they aren't very historical. There is only a handful of examples of it happening, all of which are outside of our timeframe/area of the map we represent.

On the other hand, playing in a region with a Female Dominated/Preferential faith felt weird/played suboptimally with patrilineal marriages being the default, so we fixed that by making matrilineal marriages the norm there. :)
