I don’t think DevOps leaders are claiming DevOps should be fully integrated so much as there should be a culture of collaboration and empathy, shared metrics and incentives, and preference for end to end automation... rather than antagonistic “throw it over the wall”, “I’m a dev and am too important to be paged” behaviour, etc., which has nothing to do with skill specialization.

Good contracts lead to good collaboration. Kubernetes provides the foundation for a solid end to end contract for managing complex systems automatically. It’s incomplete, but extendable.
