I'm not suggesting zfs itself change. I'd like a porcelain for people with very simple needs where zfs is almost overkill, for people who just want better data integrity and quicker backups on their main machine, for example.

I think zpool is unnecessary as an additional command. For example, `zfs scrub`, `zfs destroy [pool | dataset]`, `zfs add`, `zfs remove` would all have clear meanings. There may be a couple commands that would need explicit disambiguation with a flag like `zfs create`.
