That section makes my point for me. From the text:
(a) That IPng hosts can also use IPv4 or
(b) There is translation by an intermediate system
And that "The transition plans espoused by the various proposals are simply different combinations of the above."
Those options are precisely equivalent to dual stack and NAT64 respectively. No method of extending the address space van avoid doing one of the two.
Amusingly, it even predicts the situation today, noting that "Experience would tend to show that all these things will in fact happen, regardless of which protocol is chosen."
The mistake the committee made was dismissing NAT immediately instead of standardizing and approach alongside dual stack, to provide operators with options.
