How often does this logline occur when a pod is terminated?

Many. :-). Like for everything the reconciler touches. To be honest, it's not that big a deal, and probably something that will only be seen when running kuttl tests. But I found it very annoying, so I submitted the PR.

Would it make sense to end the reconciling with by returing nil if the reason is a terminating pod? That way the user gets informed that something did not work and we would get rid of all the unnecessary log lines?

return err
