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.

Yes, we need to keep an eye on this and argue against lowering TTLs
across the board for little good reasion.
