Some people are interested in learning how things work. In that case the main page's description is enough to get them going. I don't think that every project needs to be treated like a commercial product. This kind of project usually doesn't have a direct value to consumers but prepares the ground for other projects. It can help better understand the OS and help jailbreak IOS. Or provide drivers to install OSX on a PC or a VM and then allow cross-OS browser testing. Or maybe help a wine-like project for OSX apps. Who knows but without that project all these might not happen because the barrier to entry might be too high.
