I agree with all aspects.

But I do ask:

Do you (the ISP) control the CPE (modem / ONT)?  Could you push the 
VxLAN (or maybe MPLS) functionality all the way into it?

This would have the added advantage of a (presumably) trusted device 
providing the identification back to your core equipment.

Perhaps even minimal L3 routing w/ DHCP helper such that the customer 
saw the CPE as the default gateway.  (Though this might burn a lot more 
IPs.  This might not be an issue if you're using CGNAT.)
