Fair enough, but what you are suggesting seems to be quite different from
what this draft is suggesting. You seem to be talking about reserving for
future use, or for lab environments that never connects to any other part
of the Internet, whereas this draft is just suggesting that everyone
should use these ISO 3166 reserved codes as a 192.168 free-for-all instead
of .lan or .home or whatever they are currently squatting on.

I.e. the proposed use case is already widely deployed and known to be a
bad idea.

The intro to this draft talks about things like x- which has been
deprecated since RFC 6648. It mentions some situationw where .test or
.invalid would seem to be the right things to use, but it doesn't say why
not. It lists a bunch of TLDs that are being squatted by devices that
ought to move to home.arpa instead, but doesn't say why we have given up
on that idea after only a couple of years, or why we should expect them to
move to ISO 3166 reserved codes when they haven't moved to home.arpa.

Tony.
