Ok, so you will never have a signature in the zone where there is no DNSKEY?

The Signer Engine will do a smooth transition between keys, but in
this case you will have a signature that is valid for a year extra. At
some point will the Enforcer remove the DNSKEY, because it thinks that
all of the signatures have been replaced.
