We do not normally allocate a range for a POP which again is subnetted to 
customers. The reason is that a customer might move (and they do) and want 
to keep its range. We might also have several POPs in the same place, and 
moving the customer to another POP for some valid reason. This is what we 
also do with v4 (we don't use iBGP for /32 ppp links and similar services 
obviously, they are aggregated).

As long as the prefixlen is smaller than /128 they can always subnet.
Arguing wether 18446744073709551616 or 17592186044416 ips is enough for 
subnetting is probably not a good idea.
