It makes sense to have a special user ID without an email address. With most email addresses you cannot be sure to have them forever. If you revoke a User ID because you don't use the address any more then you lose all the certifications for this user ID. But you will never lose your name (even if you marry or the like there is usually little reason to revoke that user ID). So you keep the certifications for this ID at any rate. And you can use the comment for this ID for a statement about the key itself: "everyday key with secure offline main key and key policy"
