I see the flip side, the "cost" on being made the "escape goat" because the lens is only the developer is a fault. Verse the team owning the complete system. Which is still a toxic mindset to be trying to minimize perceived punishment. Or if the environment is not collectively responsible aka blaming then that is the problem.

But the high level point of framing I think is very on point. You can only justify altering that which you measure, and if you only blame/measure/inspect the developer, you are missing stuff.
