By definition it's an absolute maximum of 8% of people will see each path per playthrough and I would expect the majority of players would be single class. So this is content about 1-2% of players will see. There's room for niche content to flesh out playthroughs but it really has to be super impactful to be worth considering. This rings of a feature that might be worth considering once the game has been in development for 30 years.
