There is a theory that a non-trivial number of ISPs will filter at ARIN's 
defined prefix lengths, and therefore deaggregation beyond those lengths 
will be pointless unless one only wants the block(s) for private use --  
which none of us should care about.

Of course, if ISPs are willing to accept black/gray market /24s in /20 
space, they'll get what they've asked for (i.e. routers falling over).
