> Unfortunately with IPv4 I have seen many cases where people buy routers with wireless interfaces instead of (layer-2) wireless access points. Usually because the routers are cheaper and easier to get. They then plug the WAN port of the second router into one of the LAN ports of the first router and do NAT twice. With IPv4 this usually works well enough for them.

It's anecdotal evidence, but I also see this a lot; two or even three
layers of NAT is not uncommon.
