Review Comment:
As a side note I think it's better to make sure `dropDeleteFilesOlderThan`
does work. We have encountered tables that have many old EQ deleted files that
were compacted and no longer apply to any data files, but were not removed from
the table's manifests.
Note that some manifests contain only irrelevant deletes and would not
opportunistically get re-written for other purposes. Also, ReWriteManifests
currently ignores delete files.
