My assumption is that these events will be enabled for audit mode when one is interested in finding out what their crypto operations looks like. Periodic events are good but for such operations I think it's critical that we capture all such crypto calls to ensure that admins get a good picture of what's been used/called.

I remember we had this discussion a few years back and maybe we need both? Some events for audits and some that can be detected by the JMC rules engine in a normal recording?

Perhaps it's time to introduce a parameterized setting, similar to what we have for GC and compiler, where user can specify levels. From JDK 17, they can be specified on command line, i.e. 

$ java -XX:StartFlightRecording:security=off/normal/debug/audit 

This would lower the bar and make the events useful to more people.

We can do this in another JBS issue.
