I wanted to be mad but you state that people could keep their full names if they wanted and that you just wanted an option for a single name. I think that's a pretty fair request... I have no real idea if their server could be set up in a way to process a single-named character since what if someone had your full name as their first name; it might cause some issues.

But that said, if it's possible and something people want, I think it would be pretty fine... maybe not everyone wants a last name, or wants others knowing their character's mysterious last name. I'd say maybe they even just want a "title" though there's a title system so, I dunno.
