I think the demand for any solution to the unclean array is indeed low
because of the small probability of a double failure. Those that want
more reliability can use a spare drive that resyncs automatically or
raid6 (or both).

A spare disk would help, but note that raid6 does not decrease the probability of the silent corruption problem. Losing one disk in a raid6 still means that you are degraded (i.e., you rely on parity to recalculate data, so an incomplete stripe write means corruption).
