This sorta assumes specialization isn't a thing, or isn't valuable.
But we are talking about devops in the context of gruntwork. Which is targeting developers/dev teams and then making unsubstantiated claims about those devs' understanding. That's why I say what I say.
People who propose that managing their precious infrastructure cannot be bestowed on those inferior developers are the real hindrance to any business which want to go forward fast. They simply don't realize that the lack of decentralization of project management and lack of empowering teams creates a terrible communication overhead and grotesque, half baked solutions.
