The point of a cache is to avoid network round trips to re-fetch or re-validate data while it is in the cache. The DNS protocol tells the cache how long the zone publisher promises that the data will be valid. The cache can therefore store it without doing any extra work to re-examine the data for that period of time. If you break that promise you break the cache's assumptions.
