The key benefit from my perspective is that tools like pyp2rpm, conda
skeleton, the Debian Python packaging tools, etc, will be able to
automatically generate full dependency sets automatically from
upstream Python metadata.

At the moment that's manual work which needs to be handled
independently for each binary ecosystem, but there's no reason it has
to be that way - we can do a better job of defining the source
dependencies, and then hook into release-monitoring.org to
automatically rebuild the downstream binaries (including adding new
external dependencies if needed) whenever new upstream releases are
published.

Cheers,
Nick.
