I think the problem is that in z/OS there is no "one" way of
notification (I know you are asking for one).
There are at least 2 (3 if you count z) commands to "stop an
application", "P" and ,technically "F" I know F is usually modify
but it is also used as stop.
All the applications would have to be re-written. An interface would
have to be created (again programs would have to be altered and or re-
written).
I am not against it per se it would be a few years to implement I am
sure. Plus there is an issue of timing on how things happen. I smell
an ugly up rising.

Some years ago, I suggested in MVS-OE that MVS shutdown should

Can you elaborate? Why would orderly shutdown not be A Good Thing?
"They" didn't say. Too UNIXy for them. But I'll conjecture:
Many address
spaces get dubbed nowadays by incidental use of UNIX services such as
TCP/IP. The default action for SIGTERM if a process doesn't
handle it
is that the process is terminated. This would be unwelcomed by a
process
that was waiting rather for a legacy MODIFY command to shut itself
down.
