And this is without the removal of reserved status.

There is no real reason to think it would not have been practically 
universal if that had happened a decade ago.

240/4 becoming a de-facto super rc1918 in its totality is actually a net-loss. Has 240/4 been unreserved for potential global internet purposes a decade ago, much more constructive purposes could have been standardized as well. So all the delay is not a "no harm no foul" situation.

At this point, its more like you have publicly accepted all the blame 
for the current incomplete state of IPv6 by acknowledging that you chose 
to take on the daunting task of 240/4 and refused to direct yours and 
everyone you knew efforts into IPv6, which was missing only that.
