      Starting from v7.1.0 (SERVER-79052), the _shardsvrCreateCollection command keeps in scope a fixed FixedFCVRegion for the whole duration of the operation, releasing it only when the coordinator completes.

      This could be problematic because no FCV transition is allowed on shards serving a shardCollection request.
