There is another CR (don't have its number at hand) which is about

IMHO with the above CR implemented, in most cases ZFS currently
provides *much* better solution to random data corruption than any
other filesystem+fsck in the market.
The code for the putback of 2009/479 allows reverting to an earlier
uberblock AND defers the re-use of blocks for a short time to make
this "rewind" safer.
Excellent! Thank you for the information.
