Leap-seconds are the means to an end.

Civil timekeeping - likely on this or any other planet - has a fundamental 
cadence synchronized to the mean synodic day.

It has been hypothesized that our Moon plays a significant role in making Earth 
habitable:

One can thus speculate that all intelligent and timekeeping species (not 
necessarily the same thing) face the same problem of synchronizing interval 
time with time-of-day.

Some system requirements are simply facts of nature.  An attempt to descope 
leap-seconds will inevitably result in unintended consequences.  Any cure 
requires coherent system engineering.

The ITU has no authority over the tides.
