FWIW, the 80% in the proposal is an upper limit. It basically says
once at least 80% of your production network/services are IPv6
enabled, we will consider you fully IPv6 enabled. The number may need
to be tweaked, but to omit that upper bound completely would result in
folks needing to enable 100% of their network/services.
