How is it more limiting than any other thing? There are hundreds and hundreds of G names - I'd much rather say that if they hate their name we can legally change it away from that than if they want a G name they can change it to that.
That's just one thing that's really important to me. I don't care whether or not you change your name, or if it's a girl or a boy or if they want to be a wandmaker or not, but I really want my child to be a G. Ollivander. I can compromise on loads of things, but this one is going to be a really hard one.
