Not just context but all correlation operations and variables (however
variables set explicitly via perl functions/expressions IIRC aren't
flushed).

Yeah I can see the agrument for that, but I would really expect a
SEC_SHUTDOWN only when it's really being shut down.

I don't think you are missing anything. I am not sure if it makes sense to
create events for:
PRE_SEC_RESTART - this event will be the last event that SEC sees before
reloading its configuration (HUP)
PRE_SEC_SOFTRESTART - this event will be the last event that SEC sees
before reloading its configuration (ABRT)
PRE_SEC_LOGROTATE - this event will be the last event that SEC sees
before reopening its log file and closing its outputs (USR2)
just for completeness.
I can't think of an occasion where I would send a HUP to a SEC and
want to retain the state. (Then again I don't find keeping state and
reloading it after a shutdown/restart (SIGTERM/ service restart) to be
very useful given all the caveats associated with it.)
I am interested in what your use case would be for these theoretical
events.
