I think the fairness argument is very important. However, I am not  
sure I understand what take-up you expect for the reserved space and  
that means I can't work out what proportion of the space you'd like  
reserved is ever likely to be used. What proportion is likely to be  
wastage?

One /48 gives an end-site -- not an ISP which would qualify for a /32  
anyway -- 65536 /64 networks. The majority of those assignments will  
need to be used before the end-site needs to expand its prefix from  
a /48 to a /47. What I really don't have a feel for is how many  
organisations are likely to grow out of a /48 at a single site. I can  
easily understand a single organisation wanting a separate /48 for  
separate sites in separate cities or countries - but how many are  
going to require that level of growth in single locations? Further,  
how many sites are really likely to grow 16-fold at a single location?

I think it's worth looking at the likely take-up of the reserved  
spacve before hardening the policy.
