This ticket tracks the work to determine whether 'UpdateStageParams', 'DeleteStageParams', and 'BatchedDeleteStageParams' should be public to modules outside of query. On one hand, they serve as a way for callers to configure write otpions. On the other hand, they may expose some details of write execution that modules external to query shouldn't know. 

If these are determined to be private to the query module, then part of this ticket is around finding another way to allow external modules to configure write exec plans.
