I too have a story: Snow White and the Seven Dwarfs. The fairy tale's
lesson is that it's OK to make mistakes; just make sure you learn from
them.

When the wicked step-mother offered Snow White the silver IP protocol
for her corset, Snow White quickly realised it was a mistake when it
magically tightened at the /64 boundary, restricting her breathing.
Luckily Grumpy [draft-bourbaki-6man-classless-ipv6] got scissors and was
able to cut the laces. The color quickly came back to Snow White's face.

However, it should be noted that Snow White still bought the poison
apple the following day! So let's not be like Snow White.

Back to the topic: Nobody is talking about deprecation of IPv6, it is
insincere to pretend we are. We're improving an aspect of the
specification to further the adoption and deployment of IPv6.

Kind regards,
