All of those left-pad libraries are a jest, it's trivial to do padding in those languages. I was wrong about Python and removing packages but on Nuget and Maven you can't, its not allowed.

I think it's worth noting that with Java at least, besides not allowing package removal, the namespace is tied to a unique identifier with ownership verification, so the cause of the left-pad fiasco (kik wanting his namespace) is extremely unlikely to happen in the first place.
