The public IPv4 network that will continue to exist for years, perhaps
decades. But certainly for another 5-10 years.

Actually, it will soon mean "IPv4 and IPv6"... too bad it hasn't meant
that for the last couple of years.
If I come to an ISP in 2013 with an AS number and my own IPv4 addresses,
I expect they'll be able to route them and provide significant
connectivity to a large and still extant network.

Only if they need those to be reachable by IPv6 endpoints. In 2012 there
will still be lots of IPv4 endpoints talking to lots of other IPv4
endpoints, and neither end will need to upgrade.
If an organization gets another /24 worth of IPv4 space via transfer in
2012, they'll be able to announce it and hook up another 250 endpoints
and talk to and from all those other IPv4 endpoints. And this will
probably be true in 2013, and 2014, and maybe even in 2024.

Apparently the value of "some" is "a single /10". I'm referring to 2008-5.
If that's not enough, lets see a proposal to reserve some more.

That *does* make sense. What doesn't make sense is having "applicant has
figured out how to deploy enough IPv6 to impress the analyst" as a
criteria for whether IPv4 space is needed.
