Actually, I think it does. Desktop UIs have evolved and are designed for interaction, and web UIs have evolved for display of information (that is, until very recently). There are no universally common standards for interactive controls in web UI elements as there are for desktop apps.
Obviously, webapps should not copy desktop UIs entirely. But any evolution of web app UI toward better interaction is certainly good for everyone. And because desktop apps have had a lot of time to evolve efficient interaction controls, mimicking them shouldn't be a bad thing.
