That's not the impression I get from rfc2050.

3.1  Common Registry Requirements

   Because the number of available IP addresses on the Internet is
   limited, the utilization rate of address space will be a key factor
   in network number assignment.  Therefore, in the best interest of the
   Internet as a whole, specific guidelines have been created to govern
   the assignment of addresses based on utilization rates.

   Although topological issues may make exceptions necessary, the basic
   criteria that should be met to receive network numbers are listed
   below:

                25% immediate utilization rate
                50% utilization  rate within 1 year

Based on this, I would think an ISP that is, or is about to be, multihomed
and is currently completley (and efficiently) using at least a /21 worth
of IP's and expects to fully utilize a /20 in about 1 year _should_ be
able to apply for and receive their very own /19.
