Why does FaceBook not allow a "couples page"?

I've actually emailed FB about this question, I'm yet to receive an answer though. But in all seriousness, I don't understand why they don't allow it. Instead people have to create a page with some type of funky name in the heading. It would seem easy enough to change the HTML (or whatever code the site is written in) to create this type of page. I'd love to hear from a FB moderator or someone of the sorts and the opinions of our YA crew on the matter.
