This project is solving the wrong problem. It's not the interfaces of web browsers that suck, it's the gigabytes of RAM they consume.
RAM is meant to be consumed. If your browser is using 50MB of RAM and has to swap every background tab to disk then you're not utilizing the resources of your computer, and getting a crappy user experience as a bonus.
By users, not developers.
Edit: I know, I know, I know... But you all get my point.
