I think what you are saying in a nutshell is that TripleO and Kolla compete.

I think what you are saying here is Kolla chose to compete on tooling.  I
haven't really given it a lot of thought; I'd say all are technical choices
made with Kolla had mostly to do with selecting wisely from the technical
ecosystem.

I believe it wise that you don't jump to any conclusion or solution that
does or doesn't use Helm.  I'd encourage you to understand how Kubernetes
works before making such technical choices.

All that said, there is clearly value in working together rather than
apart.  To me, that is more important then the technical choices you are
presented with.
