IPv6 adds enormous amounts of unnecessary code, complexity, attack
surface, and possible confusion, in network environments that will
continue to work just fine without any trace of it for the foreseeable
future.  I still use "no options INET6" or its equivalent universally.

That "someday", in terms of requiring IPv6, is probably at least a
decade away for my ISP.  They do have one kind of modem now that offers
IPv6 via DHCPv6, but it is not yet widely deployed, and in fact is
probably a dead-end product as it is not well liked, and they charge
extra for it, and they're still doing all new installs with other modems
by default that they do not support IPv6 on (though I'm sure the devices
themselves could be configured to support IPv6).
