This is as much about ensuring people don't make mistakes from a RP sense as well, since it means that if you later find out there was an option that better fit your theme, or decided the direction you've gone was the wrong one, or decided that your character has had a change of heart (like Cicil from FF4), you have a mechanical way to change.

It's more of a quality of life thing.
In that case some of your arguments for a lv1 human bonus feat costing 1 RP don't hold up, since you could later retrain it into something useful.
