The kinds of things I think about:
I wonder what would happen if a royal ever fell in love with someone with a really non-traditional or really dated name. Like, would they be forced to change it? The royals themselves are probably always going to name their kid something like “Charles” or “William”, but what about the person the royal marries? What if Prince William had fallen in love with a girl named Bertha instead of Catherine? Or something really 90’s sounding like Stacey or Jessica? Or her parents were hippies and she was named Rainwater or Azure or something. I mean, I don’t think they could make her change it, it just seems like they’d be generally opposed to having a Princess Destiny or a Queen Chloe.
