Uh, no, Ted, they haven't. Please refer back to Leslie's policy experience report.

Why is that so bad? Today, an organization that needs a /20 is free to go out and purchase 16 discreet /24s and advertise all of them.
We're talking about an organization that started with a /24 or a /23 expanding to a maximum of 4 /24s before the policy becomes moot
anyway. In fact, the current way for an organization that has a /24 and doesn't want to renumber to get to having 2 /24s worth of space is quite simple. Entity A creates corporation B and multihomes corporation B. Entity A moves half of their need into corporation B to qualify for an ARIN /24, then moves corporation B back inside Entity A through section 8.2.

But there is no baby and the bathwater appears to smell pretty foul at this point.

Org's today aren't forced to use contiguous subnets. With 8.3, that's only going to get a whole lot worse going forward.
