Query Optimization
As part of SERVER-47398 we removed some usages of this serialization format, preferring the new 'let' parameter instead. Once we branch for what I think will be version 5.1, we no longer have to worry about communicating with a 4.4 node which will not understand the 'let' parameter everywhere.
