I think that's reasonable.
On the other hand, I would still appreciate some feedback on the proposed
NSEC/NSEC3 -> NSEC5 transition mechanism, which is currently quite painful and
I consider it the weakest point of the proposal. I believe that finding an
alternative would make NSEC5 acceptable for more people.
Currently, the transition is done the same way as in NSEC -> NSEC3, using the
DNSKEY algorithm aliases. That time it was easy - only two aliases were
allocated for RSA and DSA with SHA-1. Right now, we have at least four
suitable algorithms: RSA with SHA-{256,512} and ECDSA P-{256,384}.
