I think what Joao was suggesting was that if the nameserver had been in NASA's v6 block, then rapid renumbering would have made it viable to demand the whole block back from NASA when the nameserver was shutdown. While this is nice in theory, I tend to agree with Randy that it is not very likely in reality for a huge organisation like NASA.
I understood Joao's proposal differently. If I remember correctly, it explicitely says that this "special IPv6 space" MUST NOT be used for anything not related to IPv6 root operation. So if an organization runs a root server, they would have to have two distinct IPv6 prefixes for "root DNS related" and "all our other stuff". If they use the same IPv6 space for both, they will experience pain, but the proposal explicitely says "do not do that". So if the root server goes away, this special prefix goes away, and the "normal" address space is *untouched* - which makes Randy agree with Joao, in a way: if we do it the "old" way, we can't take the IPv6 address away - but that is not what Joao is proposing.
