In our documents about ReadPreference said:
For queries of sharded collections, for clusters with the balancer active, secondaries may return stale results with missing or duplicated data because of incomplete or terminated chunk migrations.
Beginning in 3.6, this is still true by default. However, we now have readConcern=local/majority which makes secondaries "chunk aware".
