James Taylor commented on PHOENIX-1489:
---------------------------------------

Also, what about b/w compat? This might only stay in master, as otherwise we'd 
have to keep the legacy code around that returns normal KeyValues?

> Access column values positionally from client

> Instead of passing back separate KeyValues for data returned from the server, 
> we should access via position using our TupleProjector everywhere. This is 
> already the case for joins and aggregate queries, but not for scan queries. 
> We can modify ScanRegionObserver to use our KeyValueSchema to accomplish this.
