I like that idea. I've never felt like github forking was a pain or something, but this may solve the problem of having a lot of forks going in several directions when upstream is not proactive enough in accepting pull requests : it will be way easier for one fork to rebase an other one. One UX concern, though : it's not clear in the article if it's the case, but you should really let filter branches by owner/protected and third party ones, else it will be really hard to retrieve upstream version or features branches.
