External monitor?

I can't figure out a way to produce a notification of an impending
server shutdown if a user does a soft kill of the server process.

It's easy enough if shutdown is initiated by a management op; the op
handler can trigger the notification. But a soft kill triggers a
shutdown hook registered by the MSC ServiceContainer, and once that
starts, services start stopping semi-randomly and its too late to notify
anyone that that is going to start happening.

The MSC shutdown stuff isn't exposed, so there's no way to tie into
that. Adding another shutdown hook doesn't help as there's no
predictable order of execution.
