Answering from my position. I didn't get responsibility for more systems, or bigger projects, or things like that. They made me responsible for the technical side of production. All of it, zero wiggle room.
Overall, I would not consider myself a manager. I don't have disciplinary rights, even in my team. I guess if I want someone gone, they will leave the company, but I'm no disciplinary superior.
And in my space, technical considerations still dominate. My decisions just cost more or less, affect availability, maintainability, support of our software, alow teams to go faster.
I code less chef and terraform, yeah. I'd like to do so more. But fuck me, it's better for my team to tell people to do as my team wants. It's better for me to keep my head above single resources and servers, so we keep a tactical view.
