PDS-104895 maybe PDS-103825 and others

After #4201 merged it looks like we may have deleted some streams we shouldn't have.

This path is interestingly used in large internal product (LIP), the main difference being getRowsMultimap vs getRowsColumnRangeIterator. LIP uses the former but #4201 the latter; having heavily audited the code-path there may be a bug in the latter method.
