It's honestly thinking it's too much work. All of the errata changes to player races are improvements, meaning they're not losing anything. When I made this post originally, I though the Orc was losing something (Menacing) and gaining something else (Primal Intuition). But it turns out that Menacing is just proficiency in Intimidation, while Primal Intuition is proficiency in two skills from a list, which include Intimidation anyway. Everything else, like the Kobold, Goliath, and Triton, are all either gaining something outright like Cold Resistance or losing a negative stat modifier like the Kobold.

So there's really no reason for someone to go back unless they want to nerf their newly-more powerful character. And if they want to do that, they can use adjustments or just ignore the new feature. And with plenty of other things to work on, it's not worth any effort to build adjustments that do that for them.
