Current Behavior:

I received an error message at the command line:
$ npm unpublish my-lib@1.4.0
npm ERR! code E405
npm ERR! 405 Method Not Allowed - PUT https://registry.npmjs.org/my-lib/-rev/14-878ad331638f5b05ac5eb9a52ff15fc0 - You can no longer unpublish this package.

Expected Behavior:

I expected the package to be unpublished, like described in https://docs.npmjs.com/cli/unpublish
An other page, https://www.npmjs.com/policies/unpublish talks about "newly created packages"
The description of both pages do not match.
Anyhow, i think it should be possible to remove packages with errors within a few minutes.

Steps To Reproduce:

publish in the root directory of a before published package

npm publish

unpublish with package name and version number

npm unpublish before-published-package@1.2.3

Environment:

• OS: MacOS 10.14.6 (Mojave)
• Node: 12.18.0
• NPM: 6.14.4
