We have 10,000+ customers and by default everyone is behind CGNAT. Around 25 customers have asked for a dedicated public IP address and we usually just give them one free of charge. For our case, very low percentage actually request one.

And what percent of customers have a significant problem with it, to the extent that they either need to be offered a $5-10/mo extra /32 dedicated real address, or possibly cancel? Hopefully on sample sizes of 5000 or more. All else assuming that the customers are also dual stack v4/v6 and can reach v6 things normally without any of that traffic going through the cgnat.
