Whats happening organically is that many contributing orgs also
contribute to projects like libvirt, sqlaclhemy and so on - so there's
some 'common funding source' pattern happening - but IMO its entirely
appropriate to consider these projects as independent. Because.. they
are :).

Yah, we're rolling that out more broadly at the moment. cookiecutter
has been updated, there's a review setting -constraints as the
expected pattern in the infra manual now.
