We know both what the IPv6 addressing architecture is and what the
current IANA/RIR etc. addressing policies are - nothing is an
"unknown unknown". *Unexpected* "mass address consumption" is not
possible unless and until the current addressing policies change. It is
only those who wish to play thought games with how they could abuse
128 bit addresses that are pretending these architectural decisions and
policies don't exist and won't be enforced.
