I was looking at.
DNSSEC signatures do not need to have a long lifetime; no one cares if, in 10
years, someone can find a preimage attack against today's signed zones. This
is unlike many other uses of digital signatures, where you may have to present
evidence in court about what some did or did not sign.
It's also unclear to me what the actual deployment is of stronger algorithms,
or of code that will do the right thing if multiple signatures are present.
