The concept of a species of intelligent creature that is naturally inclined to servitude and loves it is actually a very interesting concept. There’s nothing wrong with exploring such a concept in a fictional setting.
Not that they were really explored in the Harry Potter books, but I could certainly see such an exploration being fascinating, since it is wrong to enslave a people and it is wrong to prevent them from doing what makes them happy and fulfilled…which happens to be serving.
Wasn’t 64 bit adoption largely driven by Microsoft deciding they weren’t making a 32 bit version of their next Windows at one point? It seems it might take something similar.
