So, on one side we have a probably limited number of users who have a DNS setup which is uncommon, and who tolerate periods where they receive incorrect DNS responses. On the others, we have the users who have >1 DNS servers on their local network, who experience significant periods of timeout when the first is offline, even though they have working DNS service available. For me, the second set of users ought to be getting priority, because it's a vastly common setup and users experience time outs as software failing. Ensuring that the system copes normally in the face of DNS resolver failure is a very useful and important feature.
