Sorry for the late reply, traveling.

In my case, because it's what Ubuntu "supports" for bootable root crypto ZFS, and I wanted to try it.

I've run ZFS on top of LUKS for my backup storage servers for probably over a decade now, and it works fine. But it wasn't really an option for my workstation.

That said, I'm not really sure what benefit I'm gaining from ZFS on my desktop. I've got that snapshots which are definitely nice. I've used it a couple times to go back in time. In theory I can go back if I wedge the system through package installs or an OS upgrade, but I've not done that (yet). It does slow down package installs because of taking snapshots, but that's ok generally.
