I don't understand this part:

| DNSSEC [RFC4034] validators that have been offline or have missed an
| (emergency) rollover can use trust history service to get back on
| track.  The trust history location is assumed available from the
| validator configuration.  The validator then fetches old DNSKEY
| RRsets and checks they form a chain to the latest key.

Doesn't this defeat the purpose of key rollovers?
