RFC 1035 specifies in chapter 6.1.3. that requests served from a cache
should return a TTL which has been decremented by the amount of seconds
in cache, i.e. the TTL "counts down" in the cache.
Therefore I consider any caching nameservers that do not do this broken.
Are there a significant amount of such servers out there?
Though I agree on most of the other points.
