You have to consider that even with improperly working hardware, ZFS

any length of time, you *know* that the data on it is good.
You only know this if the data has previously been read.
Assume that the device temporarily stops pysically writing, but
otherwise responds normally to ZFS. Then the device starts writing
again (including a recent uberblock), but with a large gap in the
writes. Then the system loses power, or crashes. What happens then?
