No, because the "right" TAI-based tables are incompatible with POSIX.
POSIX time is essentially civil time and if the basis of civil time
changes then POSIX will follow.

If GMT and UTC become separated so that we can no longer fudge the
definition of civil time, the disambiguation will have to be resolved
by the various civil authorities.
