and CIDR bought us time to get a replacement ready.

Despite the desire to look for indicators that preclude having to learn
something new, it really doesn't matter how much of the space is routed.
What matters is the day someone new shows up to acquire space they intend to
route, only to find the reservoir dry. The number of routing entries is an
interesting operational measure, but what counts from a protocol viability
standpoint is the remaining useful space in the IANA pool.

We can always extend the lifetime of IPv4 by restricting the allocation
policies. The point is it is long past time to wake up and face the reality
that stricter conservation is directly contrary to expanding the reach and
capabilities of the global Internet. The IETF needs to be about developing a
growing and vibrant Internet, so resisting the inevitable change is counter
productive. In that light, it is time to remove the special status of
separate working groups for IPv6, and make it the default IP protocol for
all IETF work.
