This is the preferable choice, certainly. The problem is that it needs
to be *routable* PI GUA, and that's not a promise ARIN can be in the
business of making... but if it isn't routable space, it'll only be
useful as the inside network for the NAT66. The only way for this to
work is for ARIN to give the same relatively large size blocks to
everyone, so that prefix-length filters can't be used. Again, given how
much IPv6 space there is, this might actually be the right choice... but
that just makes the "easy and cheap PI GUA" argument even harder to win.
