Hmm. That would mean that the more LOs a cluster has, the more bloat
there will be in the new cluster once the upgrade is done. That could
be quite a few gigs worth of data laying around depending on the data
inserted in the source cluster, and we don't have a way to know which
files to remove post-upgrade, do we?
