+1. While we're at it (post-1.7), we might consider a design that allows
admins to keep old values of properties, too, for auditability. I would
imagine (perhaps naively) that if were only ever appending to packed files
and updating fixed-location/fixed-width manifests, for example, much of this
I/O worry would go away.
