+there'll be such a table, I don't think there's a view for it to expose it to the public
+it's not in https://gerrit.wikimedia.org/r/plugins/gitiles/operations/puppet/+/refs/heads/production/modules/profile/templates/labs/db/views/maintain-views.yaml
+I don't know enough about AbuseFilter to know how easy it would be to write a view for this table
+https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/AbuseFilter/+/refs/heads/master/abusefilter.tables.sql#63
+you'd probably need to respect afh_deleted, and join against abuse_filter to check filter visibility?
+in order to expose a view?
