The aggregation added in SERVER-44916 and used in SERVER-45389 to find inconsistent sharded indexes relies on $setUnion providing a consistent ordering, which is not supported. Instead, the pipeline will only consider fields known to be important, like name, key, and expireAfterSeconds until SERVER-29425 adds a supported way to sort an array.
