Indeed. To me, "12.04" means nothing, it's the same as "11.04" and "10.04". Two numbers separated by a dot. "Precise Pangolin" means a lot more - it's something memorable, and still shows clearly that it's a later release than the previous ones. "Beefy miracle" is also memorable, although I don't think I remember a whole lot of their earlier codenames. I recall "Leonidas", since it's also a Lithuanian name, but not much other than that... I guess they are just not used very often, people still tend to say "Fedora XX" instead of using the codenames.
