      Currently, the TransactionRouter is inspecting command BSONs and under some conditions modifying the shardVersion and databaseVersion fields to add a placementConflictTime element to them. It would be better if this was done under the proposed RouterRole APIs instead, which is the place where the shard/db versions would be constructed and attached to the commands.

      The proposal is to dettach the placementConflictTime entirely from the ShardVersion/DatabaseVersion objects.

      You'll find a more detailed explanation in this Engineering Proposald document.
