Even with ZIL disabled any data written more than 30 seconds ago is safe.

If ZFS recovers at all, ZFS will always recover to some state it
passed through prior to the crash (modulo fsync() which I think does
fuck with the timeline).

Disabling the ZIL does not at all increase the likelihood that ZFS
won't recover at all (pool loss).

If you are not using fsync() or NFS, the ZIL is never even written at
all.
