And you're glossing over the pain points that drove the industry to coin DevOps - those times when the zip didn't contain everything it needed to run in production properly and the admin guy had to call the dev multiple times in the middle of the night because their app didn't start properly on deployment. Or the install/startup procedure wasn't documented properly. Or it changed and the document didn't get updated. Or there was a new, required environment variable that didn't get mentioned in documentation anywhere. Or a new, required library was on the dev's local workstation and not on the server. etc etc

Never had such issues, you can still do decent coordination in such hand-overs. Honestly the only issue was the inflexibility of the hardware.

As a former sysadmin who had part of his career in that paradigm, I never again want to wait until 10:30 PM to run manual production deployments handed to me by a developer and hoping their documentation was correct.

Give me CI/CD pipelines deploying containers to a k8s cluster during the day.
