Mod requests list:
Re-enable Berwyn's sub/dom content
Atani marriage alternative for people who don't want Cait involved
Ability to Kill/banish all generic encounters such as the Kitsune bandits
And number one, the ability to smack Kiyoko in her fucking mouth the moment you find out she's been a child abuser this whole time
Please and thank you.

But no seriously, I'm interested to see what you make, and what others make with this, cheers.
I literally did a series of posts on this a few big updates ago, prior to the Khor'Minos palace dance update, in which I did a fresh playthrough with never recruiting Cait, documenting everytime she got shoved into the story regardless of your actions.
My findings were that in the early content, she used to spring up a lot, almost became a jump-scare (I wanted to keep all her counters at 0, so every unwanted interaction I kept praying I saved recently). But by the time of Winter Wolf, she basically dropped off the face of the planet if you didn't recruit her. It's also about that time that Sav got very into trying to push his own minotaur girl to compete with Brienne, so I think on some level the audience apathy to dislike of Cait got to him.
