It wasn't necessarily the standard or even the majority, but we had that with Sysops whenever "the build team" or "the deployment team" was building self-serve tools.
And I definitely agree with the article here that if you're using PaaS, you don't need a DevOps team. And there's certainly a better feedback loop there.
But many will argue that PaaS _still_ isn't there yet for highly complex applications. Unless you go to a point where you basically need a team managing the eventual complexity that PaaS adds back to things for you to achieve complexity.
In any case, this is mostly pedantry. We should all strive for simplicity as much as possible, but complexity in apps breeds complexity in organizational structures. DevOps was never a silver bullet, and there probably won't ever be one.
