Sadly there have seemed to be a number of rough edges that have stuck around with ZFS native encryption, which is unfortunate given that the cross platform and remote replication advantages are fundamentally very compelling. Honestly it's kind of curious that polishing that experience hasn't been more of a priority, for commercial interests like iXsystems if no one else. Speaking of which, for people running their ZFS off a NAS the idea of just being able to offload all the encryption and FS computation to that is a compelling part of the value equation beyond sheer storage in principle too. Though that in turn (if one does it with iSCSI) runs into another seemingly neglected area of ZFS (zvols). Nothing is perfect.
