I thought that too, but I've been using it for unfuddle and I prefer it this way. It gives me a separate window and dock icon from my regular browser, and just works well with the self contained system that is Unfuddle.
Yea I can see if it has utility right now but it's really a temporary fix to the problem. I think it detracts from the better goal of making rich web apps that run without a browser and the gradual blur between desktop and web apps.
