I have made the same argument on numerous occasions and still companies and organizations have charged ahead with top-heavy and encumbered identity schemes. But now the winds are beginning to shift. "Some have told us they consider the OpenID community to lack a clear process or structure, to not solve the 'real' problems in identity (yet?), or to be only applicable for low-end problems. They are probably right; however, we think of it as the early days of Internet-scale innovation in action, where these characteristics are desirable, not detrimental... Full decentralization and a very light-weight cost structure directly attract and catalyze innovation unlike any other approach. In the end, that is why you should pay attention to OpenID."
