It's a much bigger improvement than that! Besides its URL idiocy, OpenID has no way to provide information about the user. Any web app using it is still basically forced to implement its own accounts system. CAS suffers from the same bullshit -- it's only useful when backed by LDAP, and you write a second plugin for all your webapps to load just group membership directly from LDAP.
