+Subject: Modify empty zone conflicts under exclusive mode
+
+
+Does not accept new request when exclusive mode is active. Zone table
+can be modified even after main fwd entries have been added. Ensure
+empty zones handling keeps exclusive mode active.
+
+Exclusive mode were mentioned as the only protection it had by bind
+maintainer:
+https://gitlab.isc.org/isc-projects/bind9/-/merge_requests/6637#note_308928
