The protocol for multi-document transactions on sharded clusters with
readConcern = {local|majority}
is such that requires routers to attach a placementConflictTime to the shard requests. Failure to do so could lead to correctness anomalies when transactions execute concurrenctly with DDL. This ticket is to consider adding checks on the ShardRole acquisitions to ensure that this protocol is being followed.
