Unfortunately managers rarely have incentives to do it. Why invest in being more objective if it lowers the perceived value of your successes? Your bullshitting peer that isn't doing this will get promoted instead of you.
It can also be hard to even understand what are you sacrificing and why. I recently had an example where product manager was trying to improve conversion while another team was tapping into cheap low-quality traffic. PM always looked at a global conversion and kept wondering why the conversion was dropping despite his best efforts.
