Three open TODO in document about ns-revalidation HOT 2 CLOSED

This is from 2021!

and I found them in the -01

[TODO: should we keep just the simple mechanism?]

[include reference to Ghost Domains paper here]

5. Optimizations

TODO: mention possible optimizations: record whether certain
nameservers return the child NS set in their authoritative section
responses and subsequently forego the extra child NS query for a
period of time. Suggest that authoritative servers that do minimal
responses return their NS sets in response to DNSKEY queries, and
resolvers that see such behavior may also subsequently forego the
extra child NS query (from Olafur G.).

6. Re-delegations and Delegation Removals

TODO: mention in more detail what to do when resolvers observe
redelegations or removal of delegations at the parent. A quick
initial summary follows.

These are done. Thanks Shumon
