I think it's just the opposite, as LLMs feed on human language. "You are a scrum master." Automatically encodes most of what the LLM needs to know. Trying to describe the same role in a prompt would be a lot more difficult.
Maybe a different separation of roles would be more efficient in theory, but an LLM understands "you are a scrum master" from the get go, while "you are a zhydgry bhnklorts" needs explanation.
