For this particular nomenclature issue the ITU-R Radiocommunication
Assembly and the World Radio Conference failed to achieve consensus
at their meetings earlier this year.  Their result is the text
Resolution 653 (WRC-12)
which has become
WRC-15 Agenda Item 1.14
as seen here

Given the unclear outcome of the ITU-R process I recommend stability
rather than change for this issue, at least until the outcomes from
RA-15 and WRC-15 are known.
