I really like the idea of adding a column to the IPv4 and IPv6
special-purpose address space registries, and maybe that is even a better
solution than changing IPv4 and IPv6 locally-served DNS zone registries at
"Expert Review." Adding a column to the two special-purpose address space
registries would ensure that the locally-served DNS zone registries are
considered when special-purpose address space is added. In fact, I'm pretty
sure that if there were a column, RFC9637 would not have forgotten the
addition to the locally-served DNS zone registries.

Thanks.
