The current ITU proposal would have the effect of moving the coupling of
the Earth's rotation from the time that is broadcast (now called UTC) to
the timezones that local governments promulgate. While not explicitly
stated in the proposal something like this would naturally happen every
few hundred years.

I'd be willing to agree that "Coupling of Civil time to the earth is
required." Coupling of the successor to UTC isn't required, or at least
there's not consensus that it is required.
