The variable was added to behave as you suggest it should.  The code
says (gnus-agentize):

  (unless gnus-agent-covered-methods
    (mapc
     (lambda (server-or-method)
       (let ((method (gnus-server-to-method server-or-method)))
         (when (memq (car method)
                     gnus-agent-auto-agentize-methods)
           (push (gnus-method-to-server method)
                 gnus-agent-covered-methods)
           (setq gnus-agent-method-p-cache nil))))
     (cons gnus-select-method gnus-secondary-select-methods))))

And gnus-agent-covered-methods should be read from
~/News/agent/lib/servers.  So only when g-a-c-m is nil should the auto
agentizing happen.  Hm.  I guess if you deagentize all your servers,
they would be auto-agentized again.  But if no servers are agentized,
what's the point if using the agent?  Perhaps it should disable itself
in that case.
