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.
