My recollection (and I was not involved in the actual
discussions taking place) was that the use of IANA's
ICD value for this purpose left no possibility of any
other potential use, and was thus considered too restrictive.
The new AFI value was a way to avoid this limitation (although
it clearly was not the only possible solution).
