Honestly, I don't see that that says anything particularly useful. When I read something like that I wonder what it is that it's really trying to say beyond what's already in the document, and it's just a distraction to me. I think it is useful to include a brief explanation of why we moved away from the PSL, because that was in the previous version. But we should be very tightly focused when we give any such background, to avoid creating distractions.
