I do not have any intention to limit customers to the /56, however for passive customers who don��t request more and whom just get their dynamic IP Address from the PPPoE Response should we just hand out /48��s and give everyone their 65,535 subnets.

Thinking about the management probably indicates that /48��s everywhere, keep some static pools, and split my /32 in half to reserve internal space and customer space. If I really get to 32k customers then I can probably justify more space for more pops etc.

I'm not a "large" customer, but I'm a lazy one. With a /48 I can encode the VLAN tag directly in the address and never worry about lookup spreadsheets again.
(my cloud providers hand over traffic at L2 at both ends of the VLAN numbering range, and VLAN translation implementations are buggy at best)
