I recently read a lot on Stackoverflow regaring packages not working. I often found, that the cause was that beginners and newcomers used “popular” packages which have already been abandoned or were not maintained since ages.
It would be really great to either flag those packages or throw a warning when adding these packages to your project.
Looks great and I will update my repos with it, but again it fail as it depends on human input if something changes which sadly doesn’t solve the issue, if anything it might actually be more confusing if a repo is active and then the maintainer abandons it without changing the status.
Maybe there could be a community-vote mechanism? You could see next to the stars the “deprecated” flags as a count, too and build your own opinion on that. A counterargument would be, that this could be misused to put bad reputation on a package.
