What are you going to do when the container solution / node.js instance / insert x component here crashes? Wait for support to do something about it when you can fix it instantly? Or when you want to deploy a gRPC / crypto daemon to communicate with your back-end?

As an experienced back-end developer and linux user I would pull my hair out if I was completely helpless in fixing an issue or implementing some side thing that requires shell access. I don't want to wait for some guy in Philippines who will be online 12 hours later to come try to fix it.
