FWIW, I agree with Scott's arguments on this.  I think everyone agrees 
that RIRs should stay out of the business of guaranteeing that 
whatever they allocate or assign are routable.  However, I can see 
only downsides in not trying to design allocation/assignment policies 
in such a manner that the routing system behaviour could be on a more 
sustainable basis.

"Must advertise the least specific superblock" is IMHO a good 
expectation is to set.
