Allow me to contact the consumers of my Package feeds
Once I create a package feed in my organization, people outside of my immediate team will start to use the packages we create. It would be great to have that information, so that if I need to update the packages in a breaking way, delete older packages that are out of service, or change the location of the feed itself I can communicate that to my dependants.
This work is in progress now and should land in a sprint or two.

Closely related to this would be finding out which packages use the package I'm about to update. (You need this to find the people affected, but it's also super useful understanding the general dependency graph of a package.)
