Comment:

 > This seems like a good addition overall. I think we should also consider
 back-porting the change to all autoupdate branches so that all updates are
 consistent.

 Going to do exactly this. In most cases this shouldn't ever actually be
 needed, but as we ship this file with all autoupdates we might as well
 have it be consistent between every version.
