I think that observation just lends further weight to the argument that the relationship between atomic time and universal time is a dynamic and unpredictable thing, which we need to handle correctly rather than pretending it doesn't exist.

That it is dynamic and unpredictable is exactly why we should not force everybody to track it.

Some people: astronomers and orbital mechanicos are obliged to care about sidereal time, regardless. Making me deal with it too is pure tax with exactly zero benefit.
