This is one the most important jobs of product managers, if you have them: building out a backlog of shovel-ready high ROI work aggregated from customer requests, user analytics, and strategic engineering efforts.
If PM is doing their job well, engineers can build and ship multiple times within a sprint without significant delays waiting to gather feedback.
I've tried this. To be frank, it's the wrong incentive. All processes will start revolving around this. It gives a great rush to the head but a false sense of security.
Despite patting ourselves on the back on our great release cycle and velocity, we never had the time to listen and adapt to our users.
We changed. We now measure how quickly we respond to any kind of feedback.
