      The predicate {$eq: null} is expected to match both null and missing values. After SERVER-66606, it should be possible to use the type counters to get the total counts of null values (TypeTag::Null) and missing (TypeTag:Nothing). We should add these counts together when we want to estimate an equality interval on null.
