Once any filesystem writes data that was corrupted in memory, the data is hard to recover. And any filesystem will serve this corrupted data if asked, since it is all that it has. This is not a ZFS specific failure mode.

Without ECC, ZFS loses one of the guarantees that it otherwise provides. But it only degrades down to how bad every filesystem is in the face of memory corruption - not worse.
