Reminds me of the same issue with CA warnings, which used to be very alarmist but often incorrect in terms of the actual danger, so users just got used to pushing "Ok I don't care." Basically, if you have something alarming show up in from of every install created prior to OS X 10.8, it will be the "boy who cried wolf" scenario.
