There's one caveat with the current implementation, though it's not a deal breaker IMO—when Delta files are deleted there's no API to determine which table versions are valid, so we delete all but the latest one in our catalog. This means there could be versions which are still working and can be queries via time-travel but are not listed in system.table_versions.
