And under the OP's proposal, those people would continue to ZFS entirely unaffected. The OP wasn't proposing changing the behaviour of ZFS, but rather "wrapping" this defined set into a well-defined recipe which could be used by people who aren't so opinionated.

This "dumbed down wrapper" wouldn't even need to be called ZFS, to avoid confusion. Personally I'd like to propose the name ZzzFS: which is ZFS made so simple you can do it in your sleep...
