What I don’t get from the article is the reasoning behind the design that the central repository “wins” over the local/override repository. How was that design chosen, not just once but in all 3 of those large package ecosystems. Did pypi/gems/node borrow their design from each other given their similarity in other aspects? Are there any situations where this behavior is desired? Does any of the other ecosystems have flaws like this (nuget, cargo..)?
