Not really.  That ship sailed long ago - class E space is effectively useless
until a large percentage of systems are upgraded to support it.  And if you're
going to be upgrading all the CPE and ISP hardware/software *anyhow*, you may
as well enable and use IPv6 and get a lot more than 268M routable addresses for
the effort.

And its presence in bogon lists will make it quite the whack-a-mole challenge.
Those of us who have been around for a while can remember all the fun when 8/8
and 12/8 were no longer bogons.  And the net was a lot smaller then, with a lot
fewer moles that needed whacking.
