>How is that different from what's being done now? There is a standardized way of determining when leap seconds are going to happen (they always happen on June 30th or December 31st when the deviation reaches about 0.6s)

It's different because you don't have to keep track of what an authority is saying or deal with the actual time adjustment except once in a century. Once in a century is acceptable since we will only deviate by around a minute at our current rate.
