> As someone unfamiliar with NPM, why does it not lock package names for a certain period of time? From [1]: > With the default registry (registry.npmjs.org), unpublish is only allowed with versions published in the last 24 hours. If you are trying to unpublish a version published longer ago than that, contact support@npmjs.com. I am kinda assuming that if npm support were to help you unpublish a package that is depended upon (they might refuse), they would prevent someone else from re-publishing to that name (they might put up their own placeholder package, like they did during the left-pad incident), but granted I can't find this stated anywhere. I think the reason re-publishing seemed to happen in this case was they weren't prepared for whatever vector allowed for the deletion of these packages.
