+1.

If we don't work on a proposal like this, I'd love to see a specific
counter proposal that doesn't violate the current protocol
specification (i.e., using a cached answer beyond its TTL) and still
avoids resolution failure when authoritative servers are forced to be
non-responsive due to huge scale DoS attacks.  Otherwise the more
likely scenario is that some vendors still keep a similar protocol
violation using marketing decoration like "smartness" while other
compliant implementors just look incompetent (and this will be a huge
incentive for the latter group to follow the former, and we'll just
see more proliferation of this violation).
