I haven’t used Ubuntu in a number of years, but they had the idea of a primary repository that was supposed to be “perfect”, and then “universe” and “multiverse” repositories (or whatever they were called) that were of varying degrees of quality, but usually decent enough. It wasn’t AUR or NUR, it was still Ubuntu community maintained, but with at least some standards (IIRC)
I wonder if introducing the idea of support tiers for packages would be helpful at all. Packages are still maintained in our monorepo, but we can apply more liberal automatic merge logic to them.
Just a random thought, maybe I’m off the mark entirely.
