I see Redox as an incubator of new developments for a low level Rust ecosystem. It's not a production ready OS, its purpose is to spark new ideas, propose alternative implementations, try on new paths, etc. I see them implementing a ZFS variant as completely in-line with this objective.

There needs to be projects like that for any kind of innovation to happen.

Why leave at that? One day it can be production ready.
