I do not believe anyone would disagree with anything you said below. We all want all objects to support IPv6 and the transition to be easy and smooth. Wouldn't it be nice if we could turn off IPv4 when we were done in a reasonably short period of time... 


1) CPEs that do support IPv6 will provide SLAAC or DCHPv6 only to objects that will accept it.
2) Some objects behind the CPE will accept IPv6 / Dual stack, most will not.
3) Many objects behind the CPE are not capable of being upgraded via software to support IPv6.
4) The average person does not know how to take a software update unless a window pops up and says 'click here to install updates'. (Extremely unlikely to be able to perform a firmware upgrade).
5) Many CPEs must be replaced to support IPv6.
6) Many customers will not replace their CPE even if a new one arrives for free.

All of these things are bad and I am sure the list could go on far longer than this one. 

- My grandfather still had a pulse phone until last year when the telephone company finally forced him to pay for touch tone and replaced his phone for him.
- X.25 is still heavily in use today (ATM machines etc)
- People still have VCRs
- People still have broadcast television
- People still have pagers

IPv4 will very likely be around for 20+ years.. Sad, but still true.
