These kinds of comments show a certain lack of sensitivity to the needs of actual network operators. Given the pace of the IPv6 transition, and the fact that even those who migrate must use some combination of NAT and IPv4 to remain compatible with most of the internet, we have no choice but to lengthen the lifetime of IPv4. 
No one knows how long that period will be. Do you? If you've received some divine illumination on that score, by all means publish it. If you are just evangelizing IPv6, spare us, we've heard it 100 times before.

Since IPv6 migration REQUIRES a larger IPv4 network during the dual stacking period of transition, this is a pretty "interesting" observation

That's good to hear.
