CPE devices need to talk to something. If you take that something
away you make the problem worse not better and don't say historic
is not going to result in product support going away as no one
believes that.
The boxes on the carrier end of the 6to4 tunnels will need to be
upgraded to deal with other issues and historic is likely to leave
the operators in the unenviable position of having to run relays
with known security flaws or kill the service.
