It is important for projects, now, to state their goals upfront and be clear, especially when you could have 1000s of contributors from all over the world. This is something that's new for software projects, but as open source becomes larger and more diverse its becoming more necessary. The alternative has been a community based loosely around some invisible set of rules that alienates or drives away potential contributors or sparks some drama that ends up on the top of Reddit/HN/etc.
Lifetime checks will stop working if the project gets abandoned over political issues.
