You listed two cases. One where people do treat a PR as a unit of work, and one where they don't.
I responded to the first case. Of course I ignored a claim you made about the second case. If I didn't ignore that, I would be making a strawman out of what you said, mixing up your words in a way that doesn't make sense.
