while there are still devices in homes that are IPv4-only, but it certainly doesn't reduce or remove the imperative.
I agree wholeheartedly, but I'm unsure whether or not this view is held by those who control spending and
prioritization within most, or even many, ISPs.
Mobility (and everything is inexorably becoming mobile) is an obvious place where IPv6 makes a lot of sense, for
example. But native IPv6 on one's own access networks and then gatewaying/proxying to IPv4 for actual 'Internet'
connectivity seems to be a significant direction.
