I am not worried so much about the root servers here because of the reasons you cite. The root server system is engineered to cope with hugely excessive loads already. I am worried about all the other root servers that have to deal with much lesser query loads and might feel the impact of lowered TTLs much more.
... and the impact of having it in many TLD's will be to put downward pressure on TTL's. this all needs to be looked at very carefully.
Yes, we need to keep an eye on this and argue against lowering TTLs across the board for little good reasion.
