anyway to keep recordings safe?

I haven't looked into this yet, but I imagine we can at least keep the recordings safe until the next wipe. Persisting across wipes is a different use case that same may want, which would require that they be persisted in data files.

Marking this as solved since it was addressed in v3.7.0. Keep in mind that cassettes will lose their recordings after wipe, if the plugin is configured to persist backpacks across wipes. Further improvements can be made to persist cassette recordings (and other entity data) across wipes in the future.
