My objection is that the ITU-R proposal is naive and laughably incomplete, that the process is bureaucratic rather than driven by coherent system engineering practices, that due diligence in engaging stakeholders has been completely absent.

It is the proponents of this notion who are dismissive of the rest of the world.

All use a timescale whose rate is ultimately diurnal. I contend the SI rate is not close enough. You think otherwise. Focus on the engineering requirements, not trying to avoid same.
