We need to test what we ship to customers, so we need to figure that
out first for Ansible, together with the Ansible team.
Has shipping on Red Hat CDN for Collections been defined by the
Ansible organization?

TBH, I don't think Ansible team is a part to consult with. Openstack modules are moved to Openstack repository and Ansible team has no any relation to it now.
As well as Podman modules that will be moved soon (hopefully when I find the time) to CRIO namespace (https://github.com/containers)
The whole point of Ansible 2.10 is to remove all community modules from core and takeover of responsibilities for them to interested parties.
So I think nothing should block us to build/ship the RPMs

Thanks
