I will watch the video later, but if you consider this to be wokeness (whatever that term means to you. I personally don't care much about the whole debate between wokeists and anti-wokeists), then I have to point out that this wokeness goes as far back as the sagas and legends from other cultures (and there are some anegdotical historical accounts dating more than a thousand of years ago). Uncommon? Sure. But there is enough material to warrant padding the DLC with.
Then again, you could say the same about swords - they are the most popular medieval weapon in the eyes of the mainstream, while it's axes, maces and spears (the latter in particular) that ought to be the most common weapons instead. But video gaming and movies aren't about historical accuracy as much as they are about entertainment and the rule of cool. I mean, we had some really crazy stuff going on in Crusader Kings series already. To name but a few examples: Gates to Hell and Spawn of Satan. All of this was pure fiction (or a take on the legends, such as Robert the Devil), but fitted well with the religious theme of the game.
