From a security perspective what issues do you see besides auditability? It seems like the surface area for supply chain attacks is expanded needlessly by these types of shenanigans but I'm not sure how that translates to concrete impact to a project. I suppose resources required to scan and detect a package takeover are needlessly consumed but that's more upstream/centralized.

But I'm with you, this is ridiculous and auditability alone is reason enough to avoid it. Even if you were trying to make a case for composable packages this is absurd to the point that I wonder if it's self aware criticism of npm or an inside joke.
