I don't know about the crypto design of OpenZFS, but I have been running Ubuntu 20.04 with root pool using OpenZFS crypto since it's release. You have to make a small hack to the installer to do it, but otherwise it seems to be working great. I documented the installer hack at: https://linsomniac.gitlab.io/post/2020-04-09-ubuntu-2004-encrypted-zfs/ https://linsomniac.gitlab.io/post/2020-04-09-ubuntu-2004-enc... Before that I was running my storage server using LUKS on the raw devices and ZFS on top of that, since 2008, and that worked well.
