Internal readers should default to using the kNoTimestamp ReadSource. Users of AutoGetCollectionForRead are subject to having their ReadSource changed, which is not always desirable and leads to unexpected behavior.
Since internal readers have a "local" readConcern by default, despite not originating from a command, they are still eligible for changing their ReadSource.
Only reads originating from commands should change their ReadSource.
