For instance, a lot of telecommunications depends on satellite technology, hence the sponsorship of the Future of UTC meeting by the American Astronautical Society and the American Institute of Aeronautics and Astronautics.  Modern technology depends on both kinds of timekeeping.  A conceptual model recognizing the distinction is necessary.

It is my understanding tracking satellites in low earth orbit requires millisecond level accuracy of DUT1, so these folks are already correcting the time scale that's provided to them by some amount.  While convenient to keep this value < 1s, they would have several years to update if the change happens...
