it's the wrong rubrik.  folks happy with ipv4 will need to run dual stack
in order to reach the people who will come later on and not be able to get
enough ipv4 or won't want to pay for it or are, for whatever reason, not
satisfied with THEIR ipv4-only internet services.

so expansion is a barbell.  you can run out of ipv4, or other people can,
and either way you've got to run dual-stack as soon as economically possible,
and the economics are actually quite favourable (i.e., it's kinda cheap.)
