Flag package discontinued when github repository is archived
Github repositories can enter an archived state, when this happens we should flag the package as discontinued on pub.dev (if we have a verified github link).
It seems like limited harm can come from this as the package author can just unflip the discontinued flag, and publish a new version linking to a repository that isn't archived.
This probably needs a few more thoughts, but something we could consider in the future.
Maybe we can just do an analysis to see how many packages this would even affect, before we spend too much time doing more design on this feature.
Perhaps also user reporting of discontinued package might be a good option. Something like https://aur.archlinux.org/ AUR repository for Arch Linux implemented. You can flag package as unmaintained there as its user
Still not sure how impactful this would be. Maybe we should do the analysis that @jonasfj suggested.
This would even more require us to not be occasionally rate-limited by github.
