I think this issue is not restricted to only Subuqery docTransformer. Any
DocTransformer which supports querying would have this issue in case of
multi-sharded. I think that is why the childDocTransformer response is handled
like
[this|https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/response/JSONWriter.java#L118]
Should there be a JIRA to track this??
For now, It is better to revert Documentation changes. Should the changes
mention the issue is related only to multi-sharded??

To appear in subquery document list, a field should be specified both fl
parameters, in main one fl (despite the main result documents have no this
field) and in subquery's one e.g., `foo.fl`. Of course, you can use wildcard in
any or both of these parameters. For example, if field title should appear in
categories subquery, it can be done via one of these ways.

This was the previous documentation. Here, it should be made clear that
subquery's fl must be subset of main query's fl parameter. (if not already)
