I like the approach of Sourcehut to contributing. What about applying it to the Nest too? (Or even better, adding Pijul support to Sourcehut…) https://sourcehut.org/blog/2020-04-30-the-sourcehut-hub-is-live/
pijul being supported by sourcehut is a long fantasy of mine too, and now that
pijul supports text-based changes exchange (if I have understood correctly), it becomes possible to achieve that. That being said, I have no idea of the amount of works needed to get there unfortunately.
