True. However, if you wait until that point to start deploying IPv6, you’re in for a LOT of pain during that protracted emergency transition phase you just volunteered for.

OTOH, if you implement IPv6 in parallel to your IPv4 from this point forward, there’s very little additional pain and retrofitting your IPv4 can proceed at some pace until complete. After that, you can turn off IPv4 as soon as you don’t need it any more and enjoy the show while everyone else plays catchup.
