      Original Downstream Change Summary

      Previously, setQuerySettings commands containing the rawData parameter set to true would succeed. They will now fail with error code 106438.

      Description of Linked Ticket

      For legacy/"viewful" timeseries collections, setQuerySettings fails on the buckets collection (system.buckets.<X>) because they are system collections.

      With rawData queries it's now possible to query the buckets without using a system collection.

      We should evaluate whether that is supported, or rather passing rawData inside the setQuerySettings object should fail.

      (Note support is nontrivial, e.g. internal aggregation stages like $_internalBucketGeoWithin currently fail to serialize into a representative query).
