The silly part is unraid has all the pieces to do this. The btrfs file system which unraid supports for array disks could identify bitrot, and the unraid array supports virtualizing missing disks by essentially reconstructing the disk from parity and all of the other disks. Combining those two would allow rebuilding a rotted file with features already present.
My impression is unraid developers have kind of ignored enhancing the core feature of their product to much. They seem to have put a lot of effort into ZFS support which isn't that easy to integrate as it isn't part of the kernel, when ZFS isn't really the core draw of their product in the first place.
