It would be really nice. I'd be for this.

However, I know why it won't happen. SE doesn't have the staffing to police this. You know all the wonderful people that will name their baby opo-opo like "Little S***" or something. That takes GM staffing hours to go around answering tickets to put those people into "jail" and tell them to pick a new name for their pet. I'm sure they have a hard enough time with people with Chocobo names they shouldn't have, yet chocobo's can't enter cities, so they aren't even as visible.
