Is the question about why this was submitted as a separate patch, or 
about the need for the change itself? The reason for the change is 
explained in the commit text. As for submitting it separately, that was 
done to address Bryan's comments to split out the compats changes. 
Anyway, I will address the further comments from Stephen to make the 
change bisectable.
