In theory yes, in practice though, there's a lot of projects where the lead maintainer has vanished or doesn't spend a lot of time on it anymore making the future of the whole project and its forks debatable. Most forks aren't interested in taking the lead. The only exception I can think of was the nodejs fork, IO.js, which ended up being more of a political move and a kick up the arse for the Node team. A similar kick was given to the NPM team when Yarn started making waves.
