An 'extras' project without *strong* testing co-ordination with packagers such as SUSE and RedHat would end up with the consumers of the product facing the integration problems rather than resolving where they should be, within the OpenStack project itself.

I don't see your point here. From any practical perspective, most of the Nova core review work in the sub-project areas consists in formal validation of the patches (beyond the basic pep8 / pylinting done by Jenkins) or unit test requests while 99% of the authoritative work on the patches is done by the "de-facto" sub-project maintainers, simply because those are the people knowing the domain. This wouldn't change with a separate project. It would actually improve. 

Informal "Certification", to call it this way, is eventually coming from the users (including CERN of course), not from the reviewers: in the end you (the users) are the ones using this stuff in production environments and you are filing bugs and asking for new features.

On the other side, if by "extra" you mean a repo outside of OpenStack (the vendor repo suggested in previous replies in this thread), I totally agree, as it would move the project outside of the focus of the largest part of the community in most cases.
