Handling modules on PyPI that are now in the standard library?

Since it seems as I just posted about on the relevant nntplib thread that at least one exception to the standard PyPI policy was apparently made recently to hand over an existing stdlib name to a third party project, and this topic focuses specifically on PyPI projects that were superseded by standard library modules and I don’t want to drag things further off topic, I’ve opened a new thread in Packaging to discuss and hopefully come to consensus on a coherent policy on this “opposite” case, in collaboration with the PyPI admins involved:

Also, @dstufft any particular reason this is in Core Development and shouldn’t be moved to Packaging ? Seems like its much more of a packaging concern than something directly related to the development of those modules in CPython, and would attract more relevant interest being moved there, but there could be something I’m missing here.
