The `EventJitRestart` is the counterpart of the `EventCodeCacheFull`. Those who want to see the latter will probably also want to see the first one. Otherwise, you can't see when the problem is solved (performance issue or other issues related to full code cache). It may be needed to understand other events.
It is legitimate to omit non-LTS releases, but not so nice. JDK 18 is out of support.
I think a JFR user should try it and comment about the usefulness.
