That's just playing pingpong with politics.  "So the routing folks are
not able to come up with a recommendation, so we put the pressure on
the address policy group to come up with criteria who is allowed to
have a second slot in the routing table (and bonus addres space that
comes with it!) and who is not".

This is the approach that hasn't worked for the last 10 years, which is 
why the ball is in the operator's camp now.

I'm pretty sure that someone who deaggs his /32 to 65000 /48s (!) is going
to be hanged by angry mob pretty quickly...
