My wording was not that good here.

I know, some distro packagers are already looking at changes, but maybe 
this could be improved, i.e. intensified? It was more about: giving this 
more basic openstack effort a home in a project.

Yes, that's right. But distros have an interest in being able to install 
the full stack somewhere. If we have conflicting requirements preventing 
that, it should be a target of the packaging project, to fix this. 
Currently, we (as OpenStack devs) are offloading those checks (and 
fixes) completely to distributions.
