Maintainer burden is real.

As the author of BoltDB, I found that accepting and maintaining third party patches contributed to my burn out and I eventually archived the project. … Small contributions typically required hours of my time to properly test and validate them.

I am grateful for community involvement, bug reports, & feature requests. I do not wish to come off as anything but welcoming, however, I’ve made the decision to keep this project closed to contributions for my own mental health and long term viability of the project.

The simple solution is for GitHub to allow repo owners to restrict which users can interact with the pull requests feature for a given repo. This would be a great usage of the teams feature already in place.
