Except the current allocation practices seem at odds with the
goal of minimizing route table growth.  Why is it better to
allocate several non-agregatable blocks that are 'just' the
right size rather than one aggregatable block the next size
larger?  

So which do providers really want to minimize, the number
of route entries or the size of individual route entries?
