Author here. Thanks for the input. I think in some cases it can't be argued that a change is only going to be an improvement, such as in the case of npm lacking proper caching of packages until very recently. In the case of package managers, there are a multitude of them and it's up to the user to figure out which ones have which features, and then go and learn how to use them. It can be time consuming, and I believe it's more important to improve this part of the user experience than to make it easier for people to share their own packages.
