Missing Views from the APEX_DICTIONARY

A long time ago I wrote about how you can list all the apex views by querying APEX_DICTIONARY. They’re some views that are still public but are not listed in the Apex Dictionary. The following query lists these views

SELECT SYN.SYNONYM_NAME apex_view_name
  FROM all_synonyms syn, all_views av, apex_dictionary ad
 WHERE syn.synonym_name LIKE 'APEX\_%' ESCAPE '\'
   AND syn.owner = 'PUBLIC'
   AND SYN.TABLE_NAME = AV.VIEW_NAME
   AND SYN.SYNONYM_NAME = AD.APEX_VIEW_NAME(+)
   AND ad.column_id IS NULL
ORDER BY syn.synonym_name
