Agreed, looking for the same thing too.

Why change the structure of "values"?  Since the count of values, DS
names, and DS types will always be the same, why not just introduce
two new arrays, "dsnames" and "dstypes"?  Then the change would be
backwards compatible, and a configuration switch could be added to
enable this additional "DS metadata".
