mcrypt_create_iv() is great but it is about usability: not every user of the language can create a UUIDs from mcrypt_create_iv() and we should make it as easy as possible to generate unique IDs. That said, a simple uuid($version) function would not hurt the core. I would argue that this is very similar to the password_hash() API. It was possible before the password API to store password securely, but we made it way easier now, which is a very good thing. cu, Lars
