    Here is a more detailed answer. A case when a criteria for a
    subclass / superclass is based on a presence of a given relationship
    is better addressed with vertical inheritance - something we'll be
    adding in 3.0. Single table inheritance mapping requires a criteria
    based on one or more columns of the root table.
