for thing in cache application; do
I tend to think of DNSSEC as being something a $thing uses to make sure it does not receive and act on junk, and hence protect itself.
This is orthogonal to the last-mile question. If an application or a cache wants to protect itself, it needs to validate its replies. A $thing using a cache which happens to protect itself using validation should not assume that the protection is transitive.
