For me, this is a big reason why if you’re doing CGNAT you want to compliment 
it with IPv6.  

At IETF last week there was an interesting discussion about the fact that 
things like DHCPv6-PD does not explicitly say that a DHCPv6-PD prefix should be 
inserted into the routing table (!), and you may not have the tools you need to 
mange these prefixes as a result.  In DHCPv4 land of course you give out 
prefixes that are connected, but in DHCPv6-PD you may get something from a /56 
to a /64 which may mean that route needs to go into your IGP.
