It's not that people want CGNs around for a long time. It's an irrational

I don't think this is realistic with respect to a typical network operator.
It's generally expected that equipment needs to be replaced on some kind of
schedule. I would hope that by the time the next replacement time rolls
around for the CGN hardware, it would simply not be replaced. But this is
easier to do with stateless-in-the-core NATs.
