Yesterday I measured, on our busiest resolvers, the amount of replies with TTL=0 the resolvers received (from the authoritative servers). Turns out we receive around 2.3 percent replies with TTL=0. This is a percentage I can live with, and I see no reason to artificially inflate the TTL. That being said - if the percentage had been significantly higher, I would feel it was perfectly reasonable to set a minimum TTL of for instance 10s. I agree that this is a decision for each operator.
