Being a definition, this is neither right nor wrong.  It all depends
on what you are using it for. If you want to distinguish row and
column vectors, you have to use rank-2, but it is convenient to to
think of rank-1 as an equivalent of either row or column and rank-0 as
a 1x1 array. If you define transpose as a rank-2 only operation, but
allow promotion of rank < 2 to rank 2, you end up with the rules of
S+.
