There is an automatic service->host dependency that suppresses notifications
for all services that are on hosts in a non-UP state, so this seems like an
exercise in futility to me.

This would add 360*360*(2400-$services_named_PING) dependencies.
Assuming you have one PING service on each host, that's a total of
264384000 service-dependencies. *ALL* those dependencies would be
circular, so this simply cannot be how you have configured Nagios.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
