    Description

      Normally $sort uses the needsMerge flag to decide whether to return the sort key as metadata:
      https://github.com/10gen/mongo/blob/85409b314c52efaa1987d50291f2779dfa314328/src/mongo/db/pipeline/document_source_sort.cpp#L450-L455

      Presumably we will need to do the same thing for $_internalBoundedSort.
