As a developer, I'm not happy about it either. I'm now expected to write code, as fast as possible, and then handle all the ops / sysadmin tasks too, which I don't enjoy and am not really equipped to handle.
But wait, aren't you "full-stack"? That means you also know all the minutia of UI animation rendering performance optimizations across the mobile landscape, right?
Yes! Most developers don't want to do operations work. It's not their specialty, and often uninteresting to them. A good team will let developers actually develop.
