Agreed: as long as we have *both* the checks we are fine. Now that we
are close to the final wording this makes sense: before Lillehammer I
had no idea what shape would take the final resolution and having both
checks it's a rather more invasive change. Also, we had complexity
concerns, which you reported in the paper.
