No one does microservices for resume chasing anymore, because everyone is already doing it for practical reasons. I never came across a monolith that wasn't in the process of peeling responsibilities to either microservices or function-as-a-service. For project managers to open their eyes, all that's needed is something like a deployment going wrong due to a single bad commit, or things scaling weird because a background process caused a brownout, or even external teams screwing up a deployment after pushing bad code.
