    Description

      SERVER-60253 was a temporary fix to help unblock the correctness project, this is a real fix where we use this check which doesn't push group down when doingMerge=true. This flag indicates that the $group is processing data in a sharded cluster or when spilling. When sharding is implemented we will do the sharding check in mongos code, and when spill is implemented we need to remove this flag.
