Ask HN: Why not AI assisted ZFS rewrite?

A Hacker News poster asks why no filesystem developer has done a clean-room rewrite of ZFS, using LLMs under experienced engineers' guidance, to create a ZFS-like filesystem free of Oracle's licensing and upstreamable to the Linux kernel. They cite clean-room rewrites of Photoshop, MS Office and Fusion CAD, and note BcacheFS's promise ended when its core developer left the Linux kernel. The poster acknowledges filesystems need maturity and battle testing and that vibe-coding one would be foolish, framing the idea as an open-source project with the right contributors.
