Without having dug into the specifics of this particular package, I can say generally speaking that average package quality has in my view been improving a lot over the past few years; two years ago the language was pre-1.0 and people were still figuring a lot of things out. Some packages of course were excellent even then, but those tend to still be actively maintained.
