Yes, and you still don't seem be listening. You have to cooperate on
modifying events. We as a community need to respect each other's needs
and work together to solve problems. What this is saying sounds a lot
like I don't care if it breaks things, I'm gonna do it my way. Tough
luck.

You do not have to make sense of any of these events. So, what does it
really matter to you how the event is formed? What I'm asking for is
have these changes been vetted to ensure that they are not breaking
things?

Except that they are not. The design of the audit system is to save
disk space as much as possible by emitting single record events on
certain event types that are simple. To add a syscall to it adds useless
information (such as a socket address record), slows down processing,
and wastes disk space. If you get a SYSCALL record, that indicates that
you have triggered an event that the system admin has placed explicit
rules on. That is different than the common criteria required
configuration change event.

Isn't there some kind a guideline about not breaking user space?
