Recently I've learned from one of ZoL maintainers that native
ZFS encryption is not so comprehensive as GELI.
I've been told that native ZFS encryption was initially designed for one specific task:
being able to receive encrypted customer data (backups), verify its integrity without decryption,
store and then receive incremental backups later. Therefore, not all data is hidden with encryption,
for example, dataset names and some other metadata are not.
