[~smeng] would you like to contribute a patch?
Note HDFS-14034 code is around the same part of the code. It is about to get

> You can see the same LISTSTATUS request to HttpFS is missing childrenNum
> (directories only I guess), fileId and storagePolicy fields. The same applies
> to LISTSTATUS_BATCH, which might be using the same underlying calls to
> compose the response.
> Also may file another Jira to align the order of the keys in the responses.
