Why not? An ISP could send a /128 address for the internet address of a perimeter router. That address would be the ISP's gateway address to hosts on the other side of the router. With Comcrash, I get a /128 every time in addition to the /60 I request. I then assign a different /64 from that /60 to each of the four IFs (including the internet IF). I can then use public addresses all around, and I can even use NAT for the /64 on the internet interface should internal hosts use private IPv6 addresses.
