Well, you can plan for that. N+2 and all that isn't just for servers, works for humans too :)
If you haven't planned for it? Hopefully there are maintainers/contributors who care enough and have the resources to step up, figure out a plan, and execute it. If not? Have fun maintaining your own fork and finding out about security bugs on the front page of HN.
