Nonsense! However expressed the embargoed leap seconds accumulate at exactly the same rate during any particular epoch, and the long term tidal trend will present the same challenge.
Also nonsense to suggest that there is any urgency whatsoever since the current UTC standard is practical for many centuries even without expanding beyond December and June. This is a manufactured crisis.
That said, the fact that we're all still here 15 years later suggests significant community interest in working on civil timekeeping issues and infrastructure in general. How much further along we would be if we hadn't just spent those 15 years attempting to quash the naive and dangerous ITU proposal being pushed by special interests.
