It is worth noting that the current IPv6 policy is not restricted to 
allocating /32s. LIRs moving large numbers of IPv4 customers to IPv6 can 
receive shorter prefixes:

   4.4. Consideration of IPv4 infrastructure

   Where an existing IPv4 service provider requests IPv6 space for
   eventual transition of existing services to IPv6, the number of
   present IPv4 customers may be used to justify a larger request than
   would be justified if based solely on the IPv6 infrastructure.

For this reason, it probably makes sense to take account of existing 
IPv4 usage when considering this issue.
