Likewise, I appreciate being able to name snapshots, but it's annoying to have to manually name the snapshot I create in order to zfs send. The solution there is probably to not make me take a manual snapshot in the first place. `zfs send` should automatically make the snapshot for me. But in general, I don't see why zfs can't default to a generic name and let me override it with a `--name` flag.
Giving it more thought, I think I would keep pool naming. What I don't like is the possibility of having pool name collisions which isn't something you have to think about with, say, ext4 filesystems. But the upshot, as you point out, is with zfs you aren't stuck using sda, sdb, etc.
