I think this is fantastic. For beginners and not so much beginners, it is a great way to start with a very complete system for developing and build on/customize it the way you like. You don't lose any customization power as others have said. I just renamed my .vimrc to .vimrc.local and that's all, everything is working plus I earned a lot of extra-plugins that I didn't even know about.
I love it, thanks to the autor/s
