Despite having entries for all tables in dba_tab_monitoring and all indexes in dba_ind_monitoring, why does the dba_object_usage view only show a few indexes being monitored for usage?

Given that the alter index <index_name> monitoring; command has been used to turn on monitoring, shouldn't all indexes that are being monitored show up in dba_object_usage?

How can I ensure that usage tracking is activated for all monitored indexes? And, if a table or index must have monitoring enabled to be populated in dba_tab_statistics and dba_ind_statistics views when its statistics become stale, why aren't all of these monitored objects reflected in dba_object_usage?
