It has been my experience that many manufacturers don't change anything
unless they *have* to.  They might this minute be scrambling to get IPv6
into their products but that could all come to a screeching halt and
they breathe a collective sigh of relief if something like this comes
about and they continue shipping v4 only devices in perpetuity.

I suppose I wish there was a way to *temporarily* allow this and not
create a mechanism for the perpetuating of manufacturers to continue to
produce v4-only devices, which they probably will if something like this
passes, particularly if done on a global scale.

I would phrase it differently.  There should be an education process
with the users that the "old" IP addresses will soon be running out and
the new system is incompatible with the old.  This shouldn't be a
"surprise" to the users.  Operators and manufacturers have known this
was coming for a very long time.  In fact, I would support a regulation
at the federal level that makes it illegal to sell an IPv4-only device
in the United States much like they did with TVs.  Maybe something like
this could be used to enable a "converter" solution until the v4 only
devices attrit but right now we have no mechanism to ensure that v4
devices go away and something like this could enable them forever.

I see it as a temporary necessity, not a permanent necessity.

The hard part to crack is how to ensure it is temporary.
