Well, that's the "audit is my private kingdom" response, right?

People are interested in collecting the audit stream without having
the full audit daemon installed. There's useful data in the audit
stream, already generated during really early boot, long before auditd
runs, i.e. in the initrd. And for smaller systems auditd is not really
something people want around.

For example, Fedora CoreOS wants to enable selinux, thus is interested
in audit messages, but have no intention to install auditd, in the
typical, minimal images they generate. See:
