Have you considered just how much heavy lifting that is? Who is going to compile the list of tags? Who is going to approve/disapprove tagable attributes and the tags themselves? How will you resolve disagreements people have? What about the case of a package maintainer that simply can't be bothered doing tags at all? I'm not against tagging per se, they can be useful. But they do have to be strictly controlled otherwise things get out of hand very quickly. Every case I've seen of software that uses a freeform tagging mechanism fails almost instantly as it becomes very inconsistent. I have one of these apps in a corporate setting right now, have you any idea how many ways people can come up with to tag the concept of "cloud"? I have tags in there where someone translated the word "cloud" to a different language! It sounded like a good idea at the time to them.... All in all, tagging is a huge amount of work and the odds of failure are high. People need to be aware of this reality.
