We need to do anything we can to facilitate aggregation, since 
(assuming there are enough addresses) this will be the thing that 
most hinders scalability.  I don't know where we stand today with 
respect to being able to handle all the routes in the default free 
zone, but we don't want to make things worse.  

Since there appear to be enough addresses, either the current 
option (/48 only) or an option that allows either /48 or /56 seem 
like the best choices.  Having an movable boundary anywhere between
/48 and /64 will definitely hurt aggregation and site mobility.

That said, with the current option, having 64K subnets for the 
network in my car seems like a bit of overkill.  This is a
case that seems to stretch the definition of a "site" in the
current addressing architecture...
