No yes, I agree with you but frankly I'm tired of the cliche that you can't measure PRs or LOC when in reality it is very much correlated with whatever you want to optimise. I do think it can be gamed, but relying on vibes and human judgement can also be gamed (which is what I tried to point out).

You are completely right that the VP can measure user satisfaction but here's the thing: that feedback loop has a much longer time period. You could also measure your company by revenue or its stock valuation. But the point is to have metrics that have a shorter latency. How can you achieve it? Its a hard problem to solve.
