Well...since cell-index is for indexing shared resources, the
cell-index values should be whatever the convention is for that shared
resource, which can be defined as whatever is convenient for that
resource.  I think that's been zero-based in every user of cell-index
so far, but there's no reason it *has* to be if a different
enumeration is convenient for the shared resource in question.
