recover_session default behavior

Hi folks, I was reading https://ceph.io/community/automatic-cephfs-recovery-after-blacklisting/ about the new recover_session=clean feature. The end of that blog post says that this setting involves a trade-off: "availability is more important than correctness" Are there cases where the old behavior is really safer than simply returning errors? It seems like this feature would not make things worse for applications. Can we make recover_session=clean the default?
