Maintaining private forks/patches is certainly not a full-time job with git rerere, it's rather trivial. I do maintain hundreds of forks/patches updated daily fully automatically, and I have to engage in manual fixups for maybe 10hrs a year. The fixes/extensions are shared, but don't expect them to be looked at. On some projects some PR will take years. And some, like OpenSSL or coreutils outright refuse to add new features, or fix code quality.
