[dns-operations] Against ghost domain name

I have some idea of workaround about ghost domain name.
When the registry must revoke the domain name, it must not remove from
1. The registry makes the null name server of that domain name.
2. The registry changes the NS RR of that domain name. The NS RR points
the null name server of above.
3. After TTL of both parent and child NS RR, the registry removes the
domain name from zone.
4. The registry cancels the null name server.
After that, there is no ghost domain name.
Is this idea correct?
However, this operation is expensive for the registry.
Thanks in advance.
