It's just a matter of a specialization. You were a backend app engineer who wasn't specialized in containers and cloud deployments. You shouldn't be expected to know everything in the software engineering landscape. The same way you're a patent attorney now and aren't expected to practice criminal law.

I like the idea, but people keep talking about "full-stack developers" and "DevOps" (or "DevSecOps").
Also, many people seem to interpret Agile as "people are completely interchangeable", which means that you need to know all technologies used in the project, because any ticket can be assigned to you.
