Adds Provides-Extra: (with longer explanation), Setup-Requires-Dist: (full text below)
Setup-Requires-Dist lives because it makes sense to list packages only needed for setup.py to run before install is possible.
The reserved extra names test and doc live. No one should mind installing a distribution and its dependencies in order to run the unit tests or generate the documentation.
Setup-Requires-Dist (multiple use) ::::::::::::::::::::::::::::::::::
Like Requires-Dist, but names dependencies needed while the distributions's distutils / packaging `setup.py` / `setup.cfg` is run. Commonly used to generate a manifest from version control.
Examples::
Setup-Requires-Dist: custom_setup_commandDependencies mentioned in `Setup-Requires-Dist` may be installed exclusively for setup and are not guaranteed to be available at run time.
+1 To this. I agree Setup-Requires and Provides-Extra are different use cases and should both be added to the spec. I think that filling in these two missing features will benefit packaging in the long run. If this idea gains some amount of acceptance I'm happy to work on an implementation of the setup-requires end of things for packaging.
