What's wrong with my comment? Yes, python has a very confusing landscape of package management tools and practices, and indeed it's a quickly moving target. But documenting this mess is not the best solution because than the very documentation becomes a quickly moving target. Package management is not the most difficult problem in the world, is it. The python community should just be a little bolder about breaking backward compatibility.
If your original comment was downvoted (I did not vote one way or another), it was probably because it contributed little. Saying you'd "like to see" something without saying why (as in your parent comment) doesn't tend to generate discussion.
