Especially as most (I guess) users of NATing CPEs only have one dynamic
IP address, of which they are generally oblivious.
I have a feeling that the first NAT box I had (maybe 12 years ago),
connected to the Internet by dial-up, where traditionally the user
inherits the IP address (singular) of the modem/gateway they dialled
into, even if they have multiple hosts on their premises.

But NAT does have the useful (I think) side effect that I don't have to
renumber my network when I change upstream providers - whether that's
once every five years like I just did with my ADSL, or once every time
the new ADSL hiccups now that I have a CPE with 3G failover.
 Seems to be about weekly, so far.
