Well, the parts I could integrate with upstream projects, such as Selenium, I already had. Much of the remaining stuff is useful in its domain and small enough in scope where on-going development really shouldn't be necessary. And the parts I thought would essentially be "dumped", I opted not to open source for precisely that reason.
