You are right. We will have to identify the various user groups that exist within Packaging ecosystem and see how best to support them. But everything you have suggested is time and effort intensive. Before I ask volunteers to devote their time on a new project (this could be unification/better user support/enabling long term contribution), I have to gauge whether there is any interest in the maintainer community to go down this avenue.
From these discussions, I will know if the maintainer community is on board with each strand of the strategy discussions. If there is interest, as a community we would delve into each strand in more detail and do exactly what you have mentioned.
