It is also interesting to note that creating a server-scoped trigger for DDL_SERVER_SECURITY_EVENTS

Msg 1082, Level 15, State 1, Procedure tr_srv_ddl_DisplayServerEvents, Line 11
“DROP_SERVER_ROLE_MEMBER” does not support synchronous trigger registration.

The trigger that fails follows:

   1: CREATE TRIGGER tr_srv_ddl_DisplayServerEvents
   2: ON ALL SERVER
   3: FOR DDL_SERVER_SECURITY_EVENTS
   4: AS
   5: BEGIN
   6:     SELECT
   7:         'tr_srv_ddl_DisplayServerEvents' 'Trigger',
   8:         'You are not permitted to perform selected action' 'Msg',
   9:         EVENTDATA() 'EVENTDATA()'
  10:     ROLLBACK
  11: END
  12: GO
  13:

Not sure why. Seems the DDL_SERVER_SECURITY_EVENTS should include only server-scoped events.

Will continue to dig in; when I find additional details I will post a follow up entry to this one.
