I don't think it'll ever make money, but I think it will reduce costs.  CGNAT boxes cost money, operating them costs money, dealing with the support fallout from them costs money.  Especially in the residential space, where essentially if the customer calls you, ever, you just blew years' worth of margin.

My residential ISP here in the UK routes me (and every other subscriber) a /56 without being asked.  (Their supplied CPE router just puts the first /64 on the LAN and refuses to process PD requests to hand out any of the other /64s, but baby steps...)

Cheers,
Tim.
