Probably not. The ITU-R has outlined four methods for this issue, see
http://www.acma.gov.au/Industry/Spectrum/Spectrum-planning/International-planning-ITU-and-other-international-planning-bodies/wrc-15-agenda-item-114
where of method A1, A2, B, C1, C2, and D not all of them remove the
leap second from UTC.
In any case, previous draft proposals have all specified a 5 year
interval from deciding to change until the change happens, so we
should plan for 5 more years of leap seconds no matter what.
