When using a Patient that has a custom name, such as "Person" or "Demographic", specifying the patientClassName in the model-info will not enable use of these functions, as "Patient" is hardcoded in the referenced snippet. Custom birthdate is supported by builder.getDefaultModel().getModelInfo().getPatientBirthDatePropertyName() , is it possible to do such a thing with the name of the Patient class as well?

Yes, this is an unintentional oversight. Marking as a bug.
