The idea with using a /16 for initial allocations is that we don't screw up the entire /0 before we know what we are doing. In the scope of a /16, I think /32 and /40 allocations are sized appropriately. The real question is why exchange points and root servers are allocated /48's. It would make sense to use a different prefix length to reduce the temptation for other /48's to pollute the table.
