You could argue that ITU-R is working out of scope, if anything this is
increasingly more an ITU-T issue, if not handled properly within CGPM.
The issue lies within ITU-R for historical reasons, but if we are to modernize
timescales and put them in modern context, then the handling of the issue could
very well be the first place to start.
