The point of overlap I see is that if the stdlib starts putting some selected modules into site-packages (so "pip install --upgrade <sublibrary>" works without any changes to pip or equivalent tools), then that also solves the "How to explicitly declare dependencies on particular pieces of the standard library" problem: you use the same mechanisms we already use to declare dependencies on 3rd party packages distributed via a packaging server. I really like the idea of those independently versioned subcomponents of the standard library only being special in the way they're developed (i.e. as part of the standard library) and the way they're published (i.e. included by default with the python.org binary installers and source tarballs), rather than also being special in the way they're managed at runtime. Versioning selected stdlib subsets also has potential to help delineate clear expectations for redistributors: Are you leaving a particular subset out of your default install? Then you should propose that it become an independently versioned subset of the stdlib. Is a given subset already independently versioned in the stdlib? Then it may be OK to leave it out of your default install and document that you've done so. > To everyone: please don't conflate these two discussions.

While I agree they're separate discussions, the workflow management one has the potential to *also* improve the user experience in cases where redistributors are already separating out pieces of the stdlib to make them optional.
